Question

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

you use the pythagorean theorem

Answer 2

so its the second one

Answer 3

or the last one

Answer 4

they have to be equal

Answer 5

so you have to see if they are equal by using the therom

Answer 6
