Presentation transcript:

Know and apply properties of angles, including corresponding, exterior, interior, vertical, complementary and supplementary angles, to solve problems and logically justify results.

Guiding Question: What is the relationship between angles when lines cross parallel lines?  Lesson Obj: I know and can apply the properties of angles formed by 2 parallel lines cut by a transversal to solve problems and justify results  Key terms Corresponding Angles Alternate Interior Alternate Exterior Same Side Interior Transversal Recall that vertical angles are always congruent (equal measures)

Guiding Question: What is the relationship between angles when lines cross parallel lines?

All past information is also still true

Guiding Question: What is the relationship between angles when lines cross parallel lines?  If you know one angle measure you know the rest because it is just the supplement of the angle you know!

THIS DOESN’T WORK WITH NON-PARALLEL LINES Guiding Question: What is the relationship between angles when lines cross parallel lines?

 Assignment: Parallel lines Worksheet(s)  Unit Test coming soon!
