Problems with angles are done on this video. Vertical angles defined.
  • What are vertical angles?
  • If 4x, 3x, 2x, and x all add up to 360 degrees, what does each angle equal?
  • If x and 112 degrees are supplementary, what does x equal?
  • If 3x and 5x - 22 are vertical angles, what does x equal and what does each angle equal?
  • Why are vertical angles equal?
This lesson goes through 3 different problems, which are similar to the problems from the previous lessons in this series, but they are a little more complicated in this lesson. Vertical angles are also used and explained in this lesson.
