Answer 6

Good.
You see clearly in the figure that you already have a pair of angles given as congruent.
Now you need a pair of sides. Can you see a pair of sides that is congruent?
You need a side of one triangle and a side of the other triangle that are congruent.
What are they?

Answer 7

AD= AC CB=CA?

Answer 8

A C

Answer 9

There is nothing in the figure that lets us conclude that.
We don't know anything about AD = AC or CB = CA.
We do know that AC = AC, correct?

Answer 10

Yes

Answer 11

Great. Let's mark that in our figure.

Answer 12

ok

Answer 13

Side AC of triangle DAC is congruent to side CA of triangle BCA.
Now we have a side and an angle
We have AS.
We need ASA.
We need one more pair of angles.
Which pair of angles must we use?

Answer 14

ASA is not simply angle, side, angle.
It has to be two angles and the included side.
The side in ASA has to be between the abgles.

Answer 15

so it is AC?

Answer 16

No. AC is the side we need to have for ASA.
The question now is which is the pair of angles we need?

Answer 17

oh ok

Answer 18

A AND C?
