6-5: Parallel Lines Review Unit 6 English Casbarro

Parallel lines have special properties. First, we need to understand how to designate lines parallel. Make a note of the following notation: Point: Ray: Perpendicular: Segment:Plane: Line:Parallel:

We have all of the same angle pairs whether the lines are parallel or not. But When they are parallel, then the angles have certain properties that can help us.

Same-side interior angles are supplementary. Corresponding angles are congruent. Alternate interior angles are congruentAlternate exterior angles are congruent

Find all of the angles. Justify your answers.

Using the properties that you know, find 2 different ways to solve this problem for y.

Find x and y by using the properties you know.

Turn in the following problems. 1.In the parking lot shown, the lines that mark the width of the spaces are parallel. Find x and y. 2. A piece of property lies between 2 parallel streets as shown in the picture. What is the relationship between the angles? What are their measures?
