Question

How to prove a triangle is a right triangle?

Answer 1

If the sides of the triangle fit into \(\large\color{blue}{ \bf a^2+b^2=c^2 }\) then the triangle is a right triangle.

Answer 2

The biggest side is supposed to be the hypotenuse labeled as `"c"`, and two smaller sides (the sum of which has to be greater than the biggest side) are the smaller legs labeled as `"a"` and `"b"`
