Question

Given: PG ≅ SG and PT ≅ ST. Prove: GPT ≅ GST.

Answer 1

P*G ≅ S*G means that multiplier G can be substracted from both sides of equation, leaving
P≅S, similiar to second case, leaving P≅S, in other words, equation doesn't change
therefore no mater what identical on both sides of equation multiplier it might P and S, doesn't

Answer 2

change
