3.1 PROPERTIES OF PARALLEL LINES 10/21

Learning Target I can identify angles formed by parallel lines and a transversal. I can use properties of parallel lines to find missing angles.

Vocab Transversal: a line that intersects two coplanar lines at two distinct points

Corresponding Angles Postulate If a transversal intersects two parallel lines, then corresponding angles are congruent

Corresponding Angles (angles in the same spot on their respected line)

Alternate Interior Angles Theorem If a transversal intersects two parallel lines, then alternate interior angles are congruent

Alternate Interior Angles (inside the parallel lines, but on different sides of the transversal)

Same Side Interior Angles Theorem If a transversal intersects two parallel lines, then same side interior angles are supplementary

Same Side Interior Angles (inside the parallel lines but on the same side of the transversal)

Naming Angles Line CD || Line EF; Name a pair of: Vertical Angles, Adjacent Angles, Supplementary Angles, Alternate Interior Angles, Corresponding Angles, and Same Side Interior Angles.

Identifying Angle Relationships Name the relationship between the angle pairs 1 and 6 2 and and 15 7 and and 15 2 and 7 10 and 11 5 and 7

Solve for u, v, x, y, and z (be able to justify your answers with the angle relationships)

The different ways you might see parallel lines

You need to be aware that parallel line relationships exist wherever you see parallel lines. This could be in shapes, too.
