Question 660865
Hi, there--
.
Try looking at the drawing, or the hypothesis (given) for a clue as to what that next step might be. You can also look at the step that comes after, if it is shown. Then try working backwards.

You're trying to uncover the chain of reasoning that gets you from the hypothesis to the conclusion.

If you are working on a specify proof, you can post it here and we'll try to help you.
