A point is an exact location. Points have no length or width. A point may be thought of as a dot on a piece of paper.
What point is shown in red?
Step 1: Find the red point. The capital letter next to the point, B, names the point. In geometry, points are normally named by a capital letter.
Point B is shown in red.
A line is a straight set of points that travel in two directions without end. Lines can be thought of as the straight lines that can be drawn with a ruler on a piece of paper. Arrows are used to show that the line extends in both directions forever.
Multiple choice questions give you a set of answers. You choose which of the given answers is correct.
line segment: Part of a line with two endpoints.
ray: Part of a line that starts at one endpoint and extends without end in one direction.
plane: A flat surface that extends in all directions without end.
Name three line segments that have point B as one endpoint.
Step 1: Line segments are named using two endpoints in any order. The symbol for a line segment is similar to that for a line, but it has no arrow. The segment that has endpoints at point A and B can be named 
or 
.
Choose any three segments that have point B as an endpoint.
A ray is named using the endpoint first and then any other point on the ray. Ray XY, or 
has an endpoint at point X, then extends forever in a direction that goes through point Y. Draw a point Y, and extend a ray through it.
Questions that do not give you solutions to choose from are sometimes called “Show Your Work” questions. You may need to fill in a blank, make a drawing or graph, or show the equations or work that you used to find your answer.
