That's right.

Answer 7

Do you have anymore information because right now not enough information is provided to show if the answer is 45 or 55?

Answer 8

What is it called when because the angles look alike that means that they are equal to one another? I forgot the term used.

Answer 9

similar ?

Answer 10

no, there is an official math term.

Answer 11

Congruent.

Answer 12

We can tell from the picture that angle 12 is congruent to 9,8, 5, 4 and 1

Answer 13

So if you know the measure of one of those angles, then angle 12 is equal to it.

Answer 14

Okay, then in that case the answer is 55?

Answer 15

Do you know that one of the other angles is 55?

Answer 16

yes, angle is 1, so 1 corresponds with 12. Right?

Answer 17

If angle 1 equals 55 then so does 12 because they correspond and are congruent.

Answer 18

Well Done!
