Precisely define an angle. (1 point)

Question

An angle is a closed plane curve with
• every point on the curve equidistant from a fixed point within the curve.
An angle is the finite section of a line between two endpoints on the line.
An angle is a line that extends
• forever in one direction for a single endpoint.

Answer 1

An angle is formed by two rays (or line segments) that share a common endpoint, called the vertex, creating a measurable figure that represents the amount of rotation needed to superimpose one ray onto the other. The rays define the sides of the angle, and the angle can be measured in degrees or radians.
