HELP PLEASE!!!!
The figure below shows two triangles EFG and KLM: Which of the following can be used to prove that triangle EFG is also a right triangle? (1 point)
A. Use Pythagorean Theorem to prove that KL is equal to c.
B. Prove that the ratio of EF and KL is greater than 1 and hence, the triangles are similar by AA postulate.
C. Prove that the sum of the squares of a and cis greater than square of b.
D. Prove that the sum of the squares of a and b is greater than square of c.​

Answer: A. Use Pythagorean Theorem to prove that KL is equal to c.

=========================================================

Explanation:

If we could show that KL = c, then we can tie together the following pairs of segments

  • EG = KM = a
  • GF = ML = b
  • EF = KL = c

Then we'd use the SSS congruence theorem to prove the triangles are congruent. The last step is to use CPCTC to conclude that angle EGF is a 90 degree angle.

Keep in mind that we need to know the actual numeric values of 'a' and 'b' to be able to determine the value for c. So without the numbers, the Pythagorean theorem isn't really useful; however, I can see where your teacher is going with this line of logic. Your teacher is effectively just laying out a basic outline more or less.

Notes:

  • SSS = side side side
  • CPCTC = corresponding parts of congruent triangles are congruent
