In the diagram below, what needs to be labeled in order to prove triangle ahl and triangle eml are congruent by the sss postulate

HL = LM

Step-by-step explanation:

We have been given a diagram in which sides AH= EM and AL=EL.

Now we need to find which statement is missing to prove that triangles AHL and EML are congruent using SSS.

SSS means (side - side - side)

Two pair of equal sides are already given so we have completed SS of SSS.

Last "S" means we need one more pair of equal sides so that must be using remaining sides HL and LM

Hence final answer is HL = LM.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
