Answer:
C
Step-by-step explanation:
6 and 8 are vertical angles. Also, it's 25 points, not 50.
Vertical angles are a pair of angles across from another and equal in measure.
1 & 3, 2 & 4, 5 & 7, 6 & 8
When two line intersect, the angles opposie each other are called vertical angles.
So for each 2 lines that intersect, there will be 4 angles total and 2 pairs of vertical angles.
