Question

Diagram in comments!
Thanks!

Answer 1

what's the question?

Answer 2

If GF is a median of isosceles GIJ then JGF= IGF
write a two column proof

Answer 3

Sorry was typing the question after I posted the diagram

Answer 4

here in trg JGF and IGF
JG=IG (given isosceles GIJ)
GF=GF (common side to both)
IF=FJ (as GF is median hence F is the mid-point of IJ)

hence trg JGF and IGF are congruent (SSS)
thus JGF= IGF

Answer 5

Thanks!
