Question

Two column proof
Given:kl=kj and gj= hl
prove: GLJ =HJL

Answer 1

Photo is basically a box with an X in it.
G----------------------H
|\ / |
| \ K / |
| \ / |
| / \ |
L ------/------\------ J

Answer 2

KG = KH ..... HL-KL = GJ-KJ (subtraction of equals)
m∠GKL = m∠HKJ ......... vertical angles
∆GKL ≅ ∆HKJ .......... SAS
m∠GLJ = m∠HJL ............. CPCTC
