What am I missing or not understanding? Found 2 solutions by Shana-D77, cholbrook74:Answer by Shana-D77(132) (Show Source):
You can put this solution on YOUR website! I'm wondering about your two steps:
3-AC=AB+BC Seg. Add. Post.
4-CE=CD+DE Seg. Add. Post.
If AC = CD and AB = DE, then how could the above be true? I drew it out. Shouldn't it read:
3-AC=AB+BC
4-CD=DE+CE ?
