Question

Tell whether the triangle with each set of side lengths is a right triangle.

(See picture)

Answer 1

Right Triangles:

(5.1, 6.8, 8.5) and (12.5, 30, 32.5)

Not Right Triangles:

(2.2, 4.5, 6.7) and (4.7, 8.6, 10.7)

Explanation:

I solved by using the pythagorean theorem (a^2+b^2=c^2)

Plug the side lengths in, the largest side length is always c. If the equation comes out true, it is a right triangle.
