PG - Segments, Angles and Angle Pairs
Terms in this set (24)
Two angles that add up to 180 degrees. The angles are supplements of each other.
Two angles that add up to 90 degrees. The angles are complements of each other.
Two angles that are formed by intersecting lines and are opposite of each other. Their measures are equal.
Two angles that form a line. These angles are supplementary.
Two angles that are next to each other and share a common side.
The exact middle point of a segment.
D is the midpoint in the diagram.
To split equally into two.
The segment in the diagram is bisected. The two pieces are congruent.
The measurement of a segment.
Exactly the same.
A line or segment that splits another segment into two equal parts.
An angle whose measure is greater than 0 degrees and less than 90 degrees.
An angle whose measure is 90 degrees.
An angle whose measure is larger than 90 degrees and smaller than 180 degrees.
The units we measure angles with.
An angle whose measure is 180 degrees. Formed by two opposite rays and makes a line.
The figure formed when two rays share a common endpoint.
Exterior of an Angle
The set of all points on the outside of an angle.
Interior of an Angle
The set of all points inside the angle.
The common endpoint of an angle.
The tool used to measure angles.
Segment Addition Postulate
This states that if a segment is cut into two pieces, then the two pieces add up to the whole segment
Angle Addition Postulate
This states that if an angle is cut into two pieces, then the two pieces add up to the whole angle.
A line, segment or ray that splits an angle exactly in half.
Sides of an Angle
