Question

The figure below shows two triangles EFG and KLM.

Which step can be used to prove that triangle EFG is also a right triangle?

Prove that the sum of a and c is greater than b.

Prove that the sum of a and b is greater than c.

Prove that the ratio of EF and KL is greater than 1 and hence the triangles are similar by AA postulate.

Prove that KL is equal to c by Pythagorean Theorem.

Answer 1

Triangle KML is a right triangle, so a^2+b^2 = KL^2

If we can show that KL = c, then we can use the pythagorean theorem to show that triangle KML is a right triangle.

So it's "Prove that KL is equal to c by Pythagorean Theorem."
