31 Parallel Lines and Transversals
Objectives:I can identify the relationships between two lines or two planesI can name angle pairs formed by parallel lines and transversals
Does an object appear larger than it really is in the front of an Ames room or in the back?
How could the use of slanted lines make objects appear larger or smaller than they really are?

The construction of the Ames room makes use of intersecting, parallel, and skew lines, as well as intersecting and parallel planes, to create an optical illusion.
Sep 76:56 AM
When segments or rays are contained within lines that are parallel or skew, then the segments or rays are parallel or skew.

Transversal: a line that intersects two or more coplanar lines at two different points
Line t is a transversal of lines q and r. Notice that line t forms a total of eight angles with lines q and r.
