Q. Illustrate Pythagorean Theorem?
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.
