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

Answer 1

A. An angle is the figure formed by two lines extending from the same point.

This definition accurately describes an angle as the space between two rays (or line segments) that share a common endpoint, which is known as the vertex of the angle.
