The Pythagorean Theorem
The Pythagorean Theorem
In a right-angled triangle, the square of the length of the hypotenuse c equals to the sum of the squares of the lengths of the other two sides a and b.
Note: A right angled triangle is a triangle that has a right angle. The hypotenuse is the side opposite the right angle.
I. Complete the equations based on the Pythagorean Theorem.
- c2 = d2 + ___
- ___ = a2 + e2
- (a+d)2= ____ + ____
Pythagoras theorem is basically used to find the length of an unknown side and angle of a triangle. By this theorem, we can derive base, perpendicular and hypotenuse form
Applications of Pythagoras Theorem
- To know if the triangle is a right-angled triangle or not.
- In a right-angled triangle, we can calculate the length of any side if the other two sides are given.
- To find the diagonal of a square.
