Geometry Angle Terms

A line segment is the point halfway between the endpoint of a segment.

• -A part of a line
• -Only has 1 endpoint
• -Extends indefinitely in one direction.

Two rays going in opposite directions.

• -Formed by 2 noncollinear rays
• -2 rays = sides

• -Angles that have the same measure.
• -Arcs on the figures indicate which are congruent.

A ray that divides an angle into 2 congruent angles.

2 angles that lie in the same plane, have a common vertex, and a common side but does not share any interior points.

2 angles that are not adjecent and are formend when 2 lines intersect (cross).

A pair of adjacent angles whose nocommon sides are opposite

*A linear pair will always sum up to 180°.

Any 2 angles

2 angles whose measure adds up to 180°.

Lines that intersect to form right angles.
