Line Segment

AB consists of the endpoints A and B and all the points on the line AB that lie between A and B

1

Ray

The ray AB consists of the initial point A and all the points on the line AB that lie on the same side of A and B lies

2

Opposite Rays

On the line AB if C is between A and B, then CA and BC are opposite rays

3

Collinear

Points, segments, or rays that lie on the same line are collinear

4

Angle

An angle consists of two different rays that have the same initial point. The rays are the sides of the angle and the initial point is the vertex of the angle

5

Acute Angle

An angle whose measure is greater than 0 and less than 90

6

Obtuse Angle

An angle whose measure is greater than 90 and less than 180

7

Right Angle

An angle whose measure is 90

8

Straight Angle

An angle with a measure of 180

9

Interior of an Angle

Every non-straight angle has an interior. A point D is in the interior of angle A If it is between points that lie on each side of the angle

10

Exterior of an Angle

Every non-straight angle has an exterior. A point D is in the exterior of angle A if it is NOT on the angle or in the interior of the angle

11

Adjacent Angles

Two angles are adjacent if they share a common vertex and side, but have no common interior points
