2. Points
have no dimension
represented by dots
named using capital letters
examples:

3. line m AB BA m Lines B A one-dimensional
made up of points and extend infinitely in both directions
named using a single, lowercase, cursive letter or named by two points on the line
symbol:
examples: A B m
line m AB BA

4. MN NM Line Segments M N one-dimensional
made up of points and terminate at two endpoints
named using the two endpoints
symbol:
examples: M N MN NM

5. YX YW Rays W X Y one-dimensional
begin at an endpoint and extend infinitely in only one direction
named using the endpoint first, then another point on the ray
symbol:
example: W X Y YX YW

7. MLN or  NLM L 6 Angles M 6 L N
formed by the union of two rays with a common endpoint (the vertex)
three ways to name an angle:
using the vertex and a point on each ray of the angle
using just the vertex
using a number
MLN or  NLM L N M 6 L 6

8. Triangles A B C the union () of three line segments
the intersection () of any two sides is a vertex of the triangle
