Identifying Geometry

Parallel Lines

• Lines that never cross, even if they go on forever.

• …is made up of rays, lines, or line segments and meet at a common (or one) point.

• Lines that cross and make a right angle (90 degrees). Think about them making a t when they cross!

• A straight row of points that goes on forever in both directions.
