In this mini-lesson we’ll state; converse of the Pythagorean Theorem, using video and explanations in own handwriting by the instructor that brings in an element of real-class room experience.

The Pythagorean Theorem Converse states that if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. It also explains how to test whether a given triangle is a right triangle or not. For example: A triangle with sides are 18, 8, 22 is not a right triangle, because 18^{2} + 8^{2} ? 22^{2}.
