C:
###### PLAY
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
