A point is a specific location in space with no size or shape.[image]

A line is a never ending striaght path.

[image]

A segment is a part of a line containing 2 endpoint and all points between them

[image]

A ray is a part of a line that extends indefinitely in one direction from a fixed point

[image]

A plane is 

[image]

opposite rays are two rays that are part of the same line and have only their endpoints in common

[image]

Collinear are when points are on the same line

[image]

Coplanar is when they are on the same plane

[image]

An angle is a figure formed by two rays with an endpoint.

[image]

A midpoint is when two things are equally cut in half by a point

[image]

A bisector is a line that seperates the other into two congruent parts

[image]

Congruent is when it is equal

[image]

A vertex is a point

[image]

An actue angle is a measure greather than 0, but less than 90

[image]

Obtuse angles are angles a measure more than 90, but less than 180

[image]

A right angle measures exactly 90

[image]

A straight angle measures exactly 180

[image]

Are two angles that measures add up to 90

[image]

Supplementary angles that measure up together to be 180

[image]

Vertical angles are opposite angles formed by the intersection of two lines

[image]

Adjacent angles are angles that are next to each other

[image]

Linear pair the two supplementary adjacent angles formed by two intersecting lines.

[image]

Perpendicular lines are lines that intersect to form a 90 angle
