|
To divide into 2 congruent parts
|
|
|
Ray
|
A line with an endpoint that extends forever in one direction
|
|
|
Angle
|
Is formed by two rays that share a common endpoint, provided that the two rays are noncollinear.
|
|
|
Vertex
|
The commom endpoint of the 2 rays
|
|
|
Sides of an angle
|
The 2 rays are the side of the angle.
|
|
|
Outgoing Angle
|
Is formed by the cushion and the path of the ball leaving the cushion. equals the measure of the incoming angle.
|
|
|
degrees
|
Is the measurment of angles
|
|

|
The geometery tool you use to measure an angle
|
|
|
measuring of an angle
|
Is the smallest amount of rotation about the vertex from one ray to the other
|
|

|
|
Transversal
|
a line intersecting two or more other lines in the plane
|
|
|
Corresponsing angles
|
If two parallel lines are cut by a transversal , then corresponding angles are congruent
|
|
|
Alternate interior angles
|
If two parallel lines are cut by a transeversal, then alternate interior are congruent

If two parallel lines are cut by a transversal, then alternate exterior angles are congruent
|
|
|
Consecutive interior
|
If two parallel lines are cut by a transversal, then consecutive interior angles are supplementry
