Answer:
Congruent angles
Explanation:
The sum of interior angles in a triangle is equal to 180°.
50 + 65 + B = 180
115 + B = 180
- Subtract 115 from both sides.
B = 65°
The angles on the line make a straight angle, so their sum is 180°.
50 + 65 + ∠2 = 180
115 + ∠2 = 180
- Subtract 115 from both sides.
∠2 = 65°
The measure of both angles is 65° so they are congruent angles.
