Example Question #1541 : Basic Geometry
Refer to the above figure.
True or false: 
False
True
False
Two rays are opposite rays, by definition, if
(1) they have the same endpoint, and
(2) their union is a line.
The first letter in the name of a ray always refers to the endpoint of the ray. Therefore, 
Example Question #1541 : Basic Geometry
Refer to the above figure.
True or false: 
True
False
False
The first letter in the name of a ray refers to its endpoint; the second refers to the name of any other point on the ray. 
As it turns out, the two rays are one and the same.
Example Question #1541 : Basic Geometry
Refer to the above figure.
True or false: 
True
False
True
Two rays are opposite rays, by definition, if
(1) they have the same endpoint, and
(2) their union is a line.
The first letter in the name of a ray refers to its endpoint; the second refers to the name of any other point on the ray. 
The union of the two rays is a line. Both criteria are met, so the rays are indeed opposite.
Example Question #1541 : Basic Geometry
Refer to the above diagram.
True or false: 
True
False
False
Three points are collinear if there is a single line that passes through all three. In the diagram below, it can be seen that the line that passes through 
Therefore, the three points are not collinear.
Example Question #1541 : Basic Geometry
Refer to the above diagram.
True or false: 
True
False
True
Three points are collinear if there is a single line that passes through all three. In the diagram below, it can be seen that such a line exists.

True or false: The plane containing the above figure can be called Plane 
False
True
True
A plane can be named after any three points on the plane that are not on the same line. 
Plane 
Example Question #1541 : Basic Geometry
Refer to the above diagram.
True or false: Quadrilateral 
True
False
False
A quadrilateral is named after its four vertices in consecutive order, going clockwise or counterclockwise. Quadrilateral 
Example Question #11 : How To Find A Ray
Refer to the above diagram:
True or false: 
True
False
False
A line can be named after any two points it passes through. The line 
The line does not pass through
