An angle with a measure equal to 90 degrees is called a __________________________.

• right angle

• obtuse angle

• acute angle

• congruent angle

Points that lie in the same plane are called ____________________.

• coplanar points

• collinear points

• line segment

• defined terms

Coplanar lines that do not intersect.

• Parallel Lines

• Perpendicular Lines

• Congruent Segments

• Parallel Planes

What are the arrows pointing to?

• Ray

• Endpoints

• Midpoint

• Vertex

lines that cross or meet and form angles

• parallel lines

• intersecting lines

• ray

an angle that forms a square corner

• right angle

• rectangle

• acute angle

What is the difference between a LINE SEGMENT and a LINE?

• Line Segments are two-dimensional, Lines are one-dimensional

• Lines can be represented on single planes; Line Segments can only be represented on multiple planes.

• Line Segments have finite lengths; Lines go on forever.

• Line segments are geometric figures; Lines are not.

Part of a line. Has one endpoint and continues on forever in one direction.
