represented as a small dot has no length, with or thickness.
2. a line
connecting two points along the shortest possible path, has no thickness and extends infinitely in both directions.
3. A plane
is a flat surface with no thickness and no boundaries. does not extend indefinitely and it does have a thickness.
4. A ray
is a half-line with its endpoint included.
5. Half-lines
any point on the line divides the line into three parts-the point and two half-lines.
6. angle
is formed by the union of two rays that have a common endpoint.
7. A ray is
called the initial side and the other the terminal side.
8. vertex
the common endpoint of and angles initial side and terminal side is the vertex of the angle.

two angles whose measures have a sum of 180 degrees
17. vertical angles
when two lines intersect the opposite angles
18. parallel lines
are lines that lie in the same plane and have to points in common.
