|
An angle whose measure is greater than 0º and less than 90º.
|
acute angle
|
|
|
Two angles that lie in the same plane, have a common vertex and a common side, but no common interior points.
|
adjacent angles
|
|
|
The intersection of two noncollinear rays at a common endpoint. The rays are called sides and the common endpoint is called the vertex.
|
angle
|
|
|
Two angles with measures that have a sum of 90º.
|
complementary angles
|
|
|
All angles in a figure have the same measure.
|
equiangular
|
|
|
A point that is neither on the angle nor in the interior of the angle.
|
exterior
|
|
|
A point that does not lie on the angle itself and does not lie in the exterior of the angle.
|
interior
|
|
|
A pair of adjacent angles which are supplementary.
|
linear pair
|
|
|
An angle measure greater than 90º and less than 180º.
|
obtuse angle
|
|
|
Two rays such that B is between A and C.
|
opposite rays
|
|
|
1. When a transversal intersects two lines, these angles are on the same side of the transversal and on the same side of the given lines.2. Angles in the same relative position in similar or congruent figures.
|
corresponding angles
|
|
|
An angle that has a measure of 90º.
|
right angle
|
|
|
An angle that has a measure of 180o.
|
straight angle
|
|
|
Two angles with measures that have a sum of 180º.
|
supplementary angles
|
|
|

|
alternate interior angles
