An angle with a degree measure less than 90.
|
Acute

|
Two angles that lie in the same plane, but have a common vertext and a common side, but no common interior points.
|
Adjacent angles
|
|
The intersection of two noncollinear rays at a common endpoint.
|
Angle
|
|
A ray that divides an angle into two congruent angels.
|
Angle bisector

|
For any 2 points A and B on a line, there is another point C between A and B if and only A, B, and C are collinear and AC+CB=AB
|
Between
|
|

|
A point is in the exterior of an angle if it is neither on the angle nor in the interior of the angle.
|
Exterior
|
|
A point is in the interior of an angle if it does not lie on the angle itself and it lies on a segment with endpoints that are on the sides of the angle.
|
Interior
