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 a + b is greater than c in triangle EFG so c2 = a2 + b2.

Prove that the sum of the squares of a and c in triangle EFG is greater than square of b in triangle KLM.

Prove that the sum of the squares of a and b in triangle KLM is greater than square of c in triangle EFG.

Prove that KL = EF so in triangle KLM c2 = a2 + b2 which makes triangle EFG a right triangle.

Answer 2

in tria !!!

Answer 3

Prove that the sum of the squares of a and b in tria !! @LilyMysterix

Answer 4

Huh?

Answer 5

Something is missing in this question ?? What u mean by Prove that the sum of the squares of a and b in tria !!

Answer 6

to prove that EFG is right you have to prove that
c^2 = a^2 + b^2

but since KLM is right => KL= a^2 +b^2

thus c must be equal to KL

the 4th choice
(Prove that KL = EF so in triangle KLM c2 = a2 + b2 which makes triangle EFG a right triangle)

Answer 7

It's the fourth choice?

Answer 8

Yep
