Answer 1

Show your work, please. What theorems are available? What postulate MIGHT it be?

Talk it out. Think out loud.

Answer 2

AAS Theorem
SSS Postulate
ASA Postulate
SAS Postulate
One of these

Answer 3

They're all to confusing, I don't get them.

Answer 4

Okay, which parts of the figure are labeled? I can't open it.

Answer 5

Can you open that picture?

Answer 6

Well, \(\angle SUT \cong \angle TVS\), so we have an Angle. Throw out SSS as a possibility.

\(\overline{SU} \cong \overline{TV}\), so we have a Side. All three remaining choices are still in play.

Now what? I noticed that \(\overline{ST} \cong \overline{TS}\). Does that help us?

Answer 7

I'm not sure. It could?

Answer 8

Is it ASA Postulate?

Answer 9

What we have established is Side-Side-Angle. That's not a valid postulate unless we know something else about the triangles. You must hunt around in your brain and in the triangles and trapezoid for a real postulate that works. You can't just guess. Think HARD!

Answer 10

I really still don't get it. I've got a notebook, but they're still so confusing. They all look similar to me.

Answer 11

From trying different examples,I still get ASA Postulate. Can you please tell me what I'm doing wrong here>

Answer 12

What do you mean that you "get" the ASA postulate? You're not counting anything or calculating anything. Can you prove another two angles are congruent?

Answer 13

I don't know. Can you please explain it to me?
