Key concepts
3 concepts
- 1
Vertical angles are angles across from each other at the intersection of two lines, and they are always equal.
- 2
When two parallel lines are cut by a transversal line, two intersections are formed, each containing two pairs of vertical angles.
- 3
To solve for unknown angles, remember that vertical angles are equal in measure, so you can set up a matching game across the intersection.
