< 1 and < 2 are congrugent angles. m < 1 = 10x - 20 and m < 2 = 8x + 2. < 1 is a(n) ? angle.

How do we figure this out? I could use some help. Thanks.

What does it mean to say that two angles are "congruent angles"?

Two angles are congruent if and only if they have the same measures.

If <1 and <2 are congruent angles, then you know

m<1 = m<2

You are GIVEN expressions for the measures of <1 and <2. Substitute those into

m<1 = m<2

Solve for x.

Once you have a value for x, you can find m<1. And when you know what m<1 is, you can tell what KIND of angle it is.
