A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6.

Which is a true statement about the diagram?

m∠5 + m∠6 = m∠1

m∠3 + m∠4 + m∠5 = 180°

m∠1 + m∠2 = 180°

m∠2 + m∠3 = m∠5

Hillary Henry · Answer 1

m∠1 + m∠2 = 180°

Step-by-step explanation:

An interior angle and its exterior angle are supplementary (they add up to 180°).

I would really appreciate it if you would mark me brainliest!

Have a blessed day!
