question 5 of 10
which of the following best describes a bisector of an angle?
a. the set of all points in a plane that are equidistant from the vertex of a given angle
b. the set of all points included between two sides of a given angle
c. the set of all points in a plane that are equidistant from two other points
d. the set of all points in a plane that are equidistant from the two sides of a given angle

Explanation:

An angle - bisector is defined as the set of all points in a plane that are equidistant from the two sides of a given angle. Option A describes points equidistant from the vertex which is not correct for an angle - bisector. Option B describes the interior of an angle. Option C describes the perpendicular bisector of a line segment (set of points equidistant from two points).

Answer:

D. The set of all points in a plane that are equidistant from the two sides of a given angle
