Example Question #1 : How To Find A Ray
Which of the following are the sides of 
The sides of an angle are two rays, both of which begin at a common vertex. Since the middle letter of the name of this angle is 
Note that 
Example Question #2 : How To Find A Ray
A ray is different from a line in that
A line can be curved but a ray is always straight
A line has a beginning and a ray does not
A ray can cross itself
One side of the ray goes on forever while the other stops
One side of the ray goes on forever while the other stops
A ray is defined by two points, one that defines the beginning, and the other that defines the direction - this ray goes on forever in whatever direction is defined by that second point
Example Question #3 : How To Find A Ray
Which of the following is not a side of 
The two sides of an angle are the two rays that compose it. Each of these rays begins at the vertex and proceeds out from there. In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is 
Example Question #1 : How To Find A Ray
How does a ray differ from a line segment?
Ray has two end points.
A line segment has two end points, a ray only has one.
A line segment continues in both directions, a ray only continues in one direction.
A line segments connects to itself forming a shape, a ray does not.
A ray has two end points whereas a line segment only has one.
A line segment has two end points, a ray only has one.
Line segment: part of a line that has two distinct end points.
Ray: portion of a line with one end point, where the other end of the line continues to infinity.
Example Question #1 : How To Find A Ray
Refer to the above diagram. The plane containing the above figure can be called Plane 
True
False
False
A plane can be named after any three points on the plane that are not on the same line. As seen below, points 
Therefore, Plane 
Example Question #1 : How To Find A Ray
Refer to the above diagram.
True or false: 
True
False
False
A line segment has two letters in its name, each of which is an endpoint. 
Example Question #2 : How To Find A Ray
Refer to the above diagram.
True or false: 
True
False
False
A segment is named with only two letters, each of which is an endpoint. 
Example Question #1 : How To Find A Ray
Refer to the above diagram.
True or false: 
False
True
True
The two letters in the name of a line segment are its endpoints in either order. Therefore, 
Example Question #1 : How To Find A Ray
Refer to the above diagram.
True or false: 
True
False
False
A ray is named with two letters, the first of which is an endpoint and the second of which is any other point the ray passes through. 
Example Question #2 : How To Find A Ray
Refer to the above diagram.
True or false: 
True
False
True
A ray is named with two letters, the first of which is an endpoint and the second of which is any other point the ray passes through. 
The ray also passes through Point
