Question

Given the three side lengths, how can you tell if a triangle is a right triangle?

Answer 1

if the sides satisfy the pythagorean’s theorem(a^2+b^2 = c^2). a and b being the legs and c being the hypotenuse. just plug in and solve. :)

Answer 2

The sample response from Edge2020 is:

Square all side lengths. If the longest side length squared is equal to the sum of the squares of the other two side lengths, then it is a right triangle.

Hope this helps :)
