• Endpoints

• Plane

The start OR end of a line

Word Bank: Angle, Ray, Endpoint

goes on forever in both directions

• Point

• Line

• Line Segment

• Ray

a part of a line that has 2 endpoints

• Vertex

• Line Segment

• Ray

• Parallel Line

a part of a line with one endpoint and goes on forever in the opposite direction

WORD BANK:

ray    parallel lines    line

When two rays share an endpoint, they form this:

• parallel lines

• angle

• Symmetry

• Polygon

two lines in the same plane that will never intersect

• parallel lines

• perpendicular lines

• intersecting lines

• vertex

two lines that intersect and form 90* angles

• Intersecting Lines

• perpendicular lines

• Line Segment

• Parallel Lines

lines that meet or cross

• Acute Angle

• Angle

• Plane

• Intersecting Lines
