1.  Deicing is a critical winter safety procedure that removes frost, ice, or snow from aircraft surfaces using heated glycol-based fluids to ensure proper aerodynamics and lift. It is a precise, regulated, and time-sensitive process, often followed by anti-icing (applying unheated fluids) to prevent further buildup before takeoff.

Key Aspects of Aircraft Deicing

• Procedure: Specialized trucks spray a mixture of heated glycol and water (typically Type I fluid) to melt and remove frozen contaminants.
• Safety Criticality: Accumulated ice disrupts airflow over wings, significantly reducing lift, making deicing essential for flight safety.
• Timing & Regulations: Deicing is performed shortly before takeoff due to "hold-over" times (the duration fluids remain effective).
• Process Duration: While taking about 10 minutes, it can cause airport bottlenecks during heavy, active winter weather.
• Locations: Performed on dedicated pads near runways.

Types of Fluids

• Type I (Deicing): Heated, low-viscosity, often orange-dyed mixture applied at 140°F–180°F to remove ice.
• Type IV (Anti-icing): Cold, viscous fluid applied after deicing to prevent ice reformation while waiting for departure.

Deicing vs. Anti-icing

• Deicing: Removal of existing, frozen contaminants.
• Anti-icing: Prevention of new, future buildup of ice.

Environmental ConsiderationsWhile not hazardous to humans, the propylene glycol-based fluids are managed by airports to prevent environmental contamination.

Note: Deicing is also used for roads and infrastructure to prevent ice, using chemical agents that lower the freezing point of water.

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle. Let us learn more about the Pythagoras theorem, the Pythagoras theorem formula, and the proof of Pythagoras theorem along with examples.

What is the Pythagoras Theorem?

The Pythagoras theorem states that if a triangle is a right-angled triangle, then the square of the hypotenuse is equal to the sum of the squares of the other two sides. Observe the following triangle ABC, in which we have BC² = AB² + AC²​​. Here, ​​​​AB is the base, AC is the altitude(height), and BC is the hypotenuse. It is to be noted that the hypotenuse is the longest side of a right-angled triangle.

Pythagoras Theorem Equation

The Pythagoras theorem equation is expressed as, c² = a² + b², where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs. Hence, any triangle with one angle equal to 90 degrees produces a Pythagoras triangle and the Pythagoras equation can be applied in the triangle.

History of Pythagoras Theorem

Pythagoras theorem was introduced by the Greek Mathematician Pythagoras of Samos. He was an ancient Greek philosopher who formed a group of mathematicians who worked religiously on numbers and lived like monks. Although Pythagoras introduced the theorem, there is evidence that proves that it existed in other civilizations too, 1000 years before Pythagoras was born. The oldest known evidence is seen between the 20th to the 16th century B.C in the Old Babylonian Period.

Pythagoras Theorem Formula

The Pythagorean theorem formula states that in a right triangle ABC, the square of the hypotenuse is equal to the sum of the squares of the other two legs. If AB and AC are the sides and BC is the hypotenuse of the triangle, then: BC² = AB² + AC²​. In this case, AB is the base, AC is the altitude or the height, and BC is the hypotenuse.

Another way to understand the Pythagorean theorem formula is using the following figure which shows that the area of the square formed by the longest side of the right triangle (the hypotenuse) is equal to the sum of the area of the squares formed by the other two sides of the right triangle.

In a right-angled triangle, the Pythagoras Theorem Formula is expressed as:

c² = a² + b²

Where,

• 'c' = hypotenuse of the right triangle
• 'a' and 'b' are the other two legs.

Pythagoras Theorem Proof

The Pythagoras theorem can be proved in many ways. Some of the most common and widely used methods are the algebraic method and the similar triangles method. Let us have a look at both these methods individually in order to understand the proof of this theorem.

Proof of Pythagorean Theorem Formula using the Algebraic Method

The proof of the Pythagoras theorem can be derived using the algebraic method. For example, let us use the values a, b, and c as shown in the following figure and follow the steps given below:

• Step 1: This method is also known as the 'proof by rearrangement'. Take 4 congruent right-angled triangles, with side lengths 'a' and 'b', and hypotenuse length 'c'. Arrange them in such a way that the hypotenuses of all the triangles form a tilted square. It can be seen that in the square PQRS, the length of the sides is 'a + b'. The four right triangles have 'b' as the base, 'a' as the height and, 'c' as the hypotenuse.
• Step 2: The 4 triangles form the inner square WXYZ as shown, with 'c' as the four sides.
• Step 3: The area of the square WXYZ by arranging the four triangles is c².
• Step 4: The area of the square PQRS with side (a + b) = Area of 4 triangles + Area of the square WXYZ with side 'c'. This means (a + b)²= [4 × 1/2 × (a × b)] + c².This leads to a² + b² + 2ab = 2ab + c². Therefore, a² + b² = c². Hence, the Pythagoras theorem formula is proved.

Pythagorean Theorem Formula Proof using Similar Triangles

Two triangles are said to be similar if their corresponding angles are of equal measure and their corresponding sides are in the same ratio. Also, if the angles are of the same measure, then by using the sine law, we can say that the corresponding sides will also be in the same ratio. Hence, corresponding angles in similar triangles lead us to equal ratios of side lengths.

Derivation of Pythagorean Theorem Formula

Consider a right-angled triangle ABC, right-angled at B. Draw a perpendicular BD meeting AC at D.

In △ABD and △ACB,

• ∠A = ∠A (common)
• ∠ADB = ∠ABC (both are right angles)

Thus, △ABD ∼ △ACB (by AA similarity criterion)

Similarly, we can prove △BCD ∼ △ACB.

Thus △ABD ∼ △ACB, Therefore, AD/AB = AB/AC. We can say that AD × AC = AB².

Similarly, △BCD ∼ △ACB. Therefore, CD/BC = BC/AC. We can also say that CD × AC = BC².

Adding these 2 equations, we get AB² + BC² = (AD × AC) + (CD × AC)

AB² + BC² =AC(AD +DC)

AB² + BC² =AC²

Hence proved.

Pythagoras Theorem Triangles

Right triangles follow the rule of the Pythagoras theorem and they are called Pythagoras theorem triangles. The three sides of such a triangle are collectively called Pythagoras triples. All the Pythagoras theorem triangles follow the Pythagoras theorem which says that the square of the hypotenuse is equal to the sum of the two sides of the right-angled triangle. This can be expressed as c² = a² + b²; where 'c' is the hypotenuse and 'a' and 'b' are the two legs of the triangle.

Pythagoras Theorem Squares

As per the Pythagorean theorem, the area of the square which is built upon the hypotenuse of a right triangle is equal to the sum of the area of the squares built upon the other two sides. These squares are known as Pythagoras squares.

Applications of Pythagoras Theorem

The applications of the Pythagoras theorem can be seen in our day-to-day life. Here are some of the applications of the Pythagoras theorem.

• Engineering and Construction fields

Most architects use the technique of the Pythagorean theorem to find the unknown dimensions. When the length or breadth is known it is very easy to calculate the diameter of a particular sector. It is mainly used in two dimensions in engineering fields.

• Face recognition in security cameras

The face recognition feature in security cameras uses the concept of the Pythagorean theorem, that is, the distance between the security camera and the location of the person is noted and well-projected through the lens using the concept.

• Woodwork and interior designing

The Pythagoras concept is applied in interior designing and the architecture of houses and buildings.

• Navigation

People traveling in the sea use this technique to find the shortest distance and route to proceed to their concerned places.
