Answer :
Final answer:
The question pertains to identifying terms related to angles in geometry, specifically regarding how an angle relates to a vertical line. Vertical angles, supplementary angles, complementary angles, and corresponding angles are the relevant terms. So, the correct answer is: a) Vertical angle
Explanation:
The question is asking about the relationship of an angle concerning a vertical line. The relevant terms to describe an angle in relation to the vertical line are as follows:
- Vertical angle: When two lines intersect, they form two pairs of opposite angles called vertical angles; these angles are equal in measure.
- Supplementary angle: Two angles are supplementary if the sum of their measures is 180 degrees, which means they form a straight line when adjacent.
- Complementary angle: Two angles are complementary if the sum of their measures is 90 degrees.
- Corresponding angle: When two lines are crossed by another line (called the transversal), the corresponding angles are on the same side of the transversal and in corresponding positions.
