Question

Which definition best describes vertical angles?

A. A pair of angles that combine to form a straight angle
B. A pair of angles whose sum is
C. A pair of angles whose sum is
D. A pair of opposite angles formed by intersecting lines

Answer 1

The answer is D; a pair of opposite angles formed by intersecting lines. Verticle angles are always opposite of each other, and their angles are an equal amount of degrees as well.

Answer 2

Option D: a pair of opposite angles made by two intersecting lines.

Explanation:

In geometry, a pair of angles is said to be vertical if the angles are formed from two intersecting lines and the angles are not adjacent. The two angles share a vertex. Such angles are equal in measure and can be described as "equal" or "congruent". Vertical refers to the vertex (where they cross).
