Q. Illustrate Pythagorean Theorem?

Ans.

You have definitely seen the Pythagorean Theorem before, so a²+ b² = c² should look familiar to you.

The Pythagorean Theorem applies to right triangles (and only right triangles), where c is the length of the hypotenuse (the side opposite the right angle) and a and b are the lengths of the legs (the other two sides).

So in the following triangle, the Pythagorean theorem states that x² + y² = 1

You can use the Pythagorean theorem in reverse to tell whether a triangle is a right triangle.
