Description
Students will be able to identify and prove angle relationships that occur with intersecting lines, perpendicular lines and parallel lines that are cut by a transversal.
Timeline
2 Week(s)
Enduring Understandings
Angles that are related by intersecting lines are either congruent to each other or supplementary to each other.
Angles are congruent when they are vertical. Alternate or corresponding angles are congruent when lines are parallel.
Any point on a perpendicular bisector is equidistant from the endpoints.



Essential Questions
What is the congruence relationship between the angle pairs formed from intersecting lines?
What is significant about points on a perpendicular bisector?
