Here are 5 related questions to expand your understanding:

1. How do you calculate the measure of an unknown angle when two lines intersect?
2. What is the sum of angles in a triangle, and how can this help in determining angle measures?
3. How do supplementary angles relate to the calculation of angle measures?
4. What is the relationship between complementary angles?
5. How can you find the measure of an exterior angle in a polygon?

Tip: When two lines intersect, the opposite (or vertical) angles are always equal.
