Problems with angles are done on this video. Transversal, corresponding, alternate and interior angles defined.
  • What does it mean for lines to be parallel and perpendicular?
  • What is a transversal?
  • What are corresponding angles?
  • What are alternate interior and alternate exterior angles?
  • If there are two parallel lines cut by a transversal, how do you find the values of the angle measures if one angle is 72 degrees?
  • If two parallel lines are cut by a transversal, and two vertical angles are a and 7x, and 7x and 2x are on the same side of the transversal, how do you the values of the angle measures?
  • How do you know which angle measures are equal in a figure with two parallel lines cut by a transversal?
  • If two angles are supplementary and one angle is 72 degrees, what is the other angle measure?
  • If 2x and 7x are supplementary, what does x equal and what is the measure of each angle?
This lesson goes through examples with parallel lines being cut by a transversal. Then, corresponding, vertical, alternate interior, and alternate exterior angles are used to solve the two problems shown in this lesson. These are very common types of problems for a Geometry class. All logic to determine the measures of the different angles is explained.
