100
These are often shown as dots to represents location.
What are points
100
This is a straight set of points, one after another, that extends in both direction forever.
What is a line?
100
A part of line which begins at one point and ends at another point.
What is a line segment?
100
This is part of a line that starts at a point then extends along the line in one direction forever.
What is a ray?
100

This is formed by two rays with a common endpoint.

What is an angle?

200
This is what we use to represent specific points.
What are capital letters?
200
A double arrow "hat" over AB.
What is a representation of a line that goes through points A and B
200
These are called endpoints of the segment.
What are beginning and ending points of the segment?
200
This is the starting point of a ray.
What is an endpoint of the ray?
200
This is the common endpoint of the rays making an angle.
What is the vertex of an angle?
300
The number of points in space.
What is infinity.
300
When two or more points are in the same line.
What are collinear points.
300
In segment NM, this is what points N and M are.
What are endpoints of segment NM.
300
What is a single arrow "hat" over the endpoint letter and a second point letter.
What is a written representation for a ray ?
300
This is the region where the points are "between" the two rays.
What is the interior of the angle?
400
This is what two lines intersect at (or what do two intersecting lines have in common?)
What is a point?
400
<-----> CD
What a line that contains points C and D?
400
___ A B
What is a line segment with endpoints A and B
400
Two or more points in the same plane.
What are coplaner points?
400
This an angle that has a vertex point B and rays that go through points A and C.
What is angle ABC?
