Has no dimension, a line has one dimension, and a plane has tow dimensions

A Point

Is a statement that is accepted without further justification

A postulate

Are points that lie on the same line

a Collinear points

Are points that lie on the same plane

A coplanar points

Consists of the endpoints A and B and all points on AB that are between A and B

THe Segment AB

Consits of the endpoints A and B and all points on AB that lie on the same side of A as B

ray AB

is the point of points that the figures have in common

Intersection of two or more figures.

If they have any points in common

Intersect.

The real number that corresponds to a point

Coordinate

Between points A an B, written AB, is the absolute value of the difference of the coordinates of A and B

Distance

Segments that have the same length

Congruent segments

Consists of two rays that have the same endpoint

Angle

Are these die of the angle

Rays

The endpoint is the

Vertex

The measures of an angle is written in units

Degrees

Two angles are... angles they have the same measure

Congruent

Measure is between 0 degrees and 90 degrees

Acute angles

Measure is between 90 degrees and 180 degrees

Obtuse angle

Measure is 90 degrees

Right angle

Measure is 180 degrees

Straight angle
