line
My length cannot be measured, but I am named by two of my points.

I do not curve. I have only one endpoint.
angle
I am measured in degrees. I have a vertex. My sides are two rays.
perpendicular line segments
We have endpoints. When two of us meet, we form one or more right angles.
parallel line segments
There are always at least two of us. We have endpoints. We always stay the same distance apart.
vertex
I am the point where two rays meet to form an angle
intersecting lines
Two of us meet.
perpendicular lines
Our lengths cannot be measured. When two of us meet, we form right angles
vertices
I am the endpoint where two sides of a polygon meet
line segment
My length can be measured. I have two endpoints
parallel lines
Our lengths cannot be measured. There are always at least two of us. We always stay the same distance apart.
