Question

How to determine if a triangle is a right triangle with pythagorean theorem?

Answer 1

Square the base, height and hypotenuse
 add the base and height together and if it equals the hypotenuse it is a right triangle
 example:
 base = 3, height = 4, hypotenuse = 5

3^2 + 4^2 = 9 + 16 = 25

5^2 = 25

25 = 25 so that would be a right triangle.
