Question

Two lines intersect to form the angles shown. Which statements are true? Please choose more than one.

m∠3=m∠1



m∠1=100° ​

m∠3=80° ​

m∠2=80°

Answer 1

Well measure 3 does equal measure 1. (I'm pretty sure?)
From what I can remember, I think the 100 degrees should equal measure 2, and measure 3 should equal measure 1?

Answer 2

The correct answers are:
m∠3=m∠1

m∠3=80° ​
