Which defines a line segment?
a. two rays with a common endpoint.
b. a piece of a line with two end points
c. a piece of a line with one endpoint
d. all points equidistant from a given point

A line segment is a piece of a line with two endpoints.

Further explanation A line segment is a piece of a straight line which links two endpoints with known coordinates without surpassing them. It is clear enough that the line segment has two endpoints. In addition to containing these endpoints, a line segment also contains all the points of the line between them. A line segment is named by its two endpoints, e.g., A line is an infinite number of points extending in opposite directions that has only one dimension.A ray is a part of a line that has one endpoint and runs indefinitely in only one direction, e.g., The length of the ray cannot be calculated.The angle is a figure consisting of two rays with a common endpoint. It can also be said that an angle is a shape formed by two rays sharing a common endpoint. Vertex is the common endpoint of the two rays that form the angle of a triangle or two sides of a polygon.  A circle represents the set of all points in a plane that are equidistant from a given point called the center of the circle.  The radius represents the line segment from a center of the circle to any point in the circle. Refer to the definition, all radii have a uniform length.

Types of Angles  

The acute angle represents an angle whose measure is greater than zero degrees and less than 90°.  The right angle represents an angle that measures 90° precisely.  The obtuse angle is an angle whose measures greater than 90° and less than 180°.  The straight angle represents a line that goes infinitely in both directions and measures 180°. Carefully differentiate from rays that only runs in one direction. Learn more  Which points are coplanar and noncollinear? Match the term with the definition: line, line segment, ray, point, vertex A line that is not parallel to either the x-axis or the y-axis represents a line that occupies a slope or in other words a gradient
