Which of the following properties does an angle exhibit?

An angle is formed when two lines or rays intersect at a common point. This intersection creates the measures and characteristics associated with angles, such as acute, obtuse, and right angles. When you think of angles, you might picture how they are visually represented in geometry—formed by the intersection of two lines.

While perpendicularity involves a specific condition where two lines intersect at right angles, and symmetry refers to a balanced or proportional arrangement, these concepts are not intrinsic properties of angles themselves. Orthogonality is a term often used in contexts such as vector spaces to refer to lines or vectors that are perpendicular to one another, but it does not apply to angles directly.

Thus, the defining property of how angles are created and understood is through the concept of intersection. Angles can only exist through the intersection of two lines or line segments, making intersection the most relevant property when discussing angles.
