Question

in the figure to the right, line m and line n are parallel. determine whether the given angles are congruent or supplementary.
∠1 and ∠7
identify whether the pair of angles is congruent or supplementary.

• supplementary angles
• congruent angles

Explanation:

Step1: Recall angle - pair relationships

When two parallel lines are cut by a transversal, corresponding angles are congruent, vertical angles are congruent, and adjacent angles that form a straight - line are supplementary. Without seeing the specific angles \(D_1\) and \(D_2\) clearly, we assume they are either corresponding or vertical angles.

Step2: Determine the relationship

Since corresponding and vertical angles are congruent, if \(D_1\) and \(D_2\) are either of these types of angle - pairs, they are congruent.

Answer:

congruent angles
