Answer 3

Okay, think of the concepts of alternate exterior angles, vertical angles, linear pairs, corresponding angles, etc.

Answer 4

okay

Answer 5

With that knowledge, what do you think the answer is?

Answer 6

c?

Answer 7

That is somewhat correct, but what's another vertical angle of angle 2?

Answer 8

5?

Answer 9

Angle 2 and angle 5 form a linear pair.
What are the two vertical angles of angle 2?

Answer 10

I'm not sure

Answer 11

You understand the concepts of vertical angles, correct?

Answer 12

yes

Answer 13

Okay, so what is directly diagonal from angle 2 on the top?

Answer 14

3

Answer 15

Correct! Now what's the other vertical angle of angle 2? I'll give you a hint, it's towards the bottom.

Answer 16

6/7

Answer 17

Angle 6 and angle 2 are corresponding angles; they are still congruent, just not vertical angles.
7 is a vertical angle, so good job! ^^

Now, what do you think the answer is now?

Answer 18
