Question

1. choose the best answer. what is the name of the pair of angles ∠abd and ∠cbf which are nonadjacent angles formed by the intersection of two lines?

Explanation:

When two lines intersect, non - adjacent angles formed are called vertical angles. Vertical angles are equal in measure and are opposite each other at the intersection of two lines. In this case, ∠ABD and ∠CBF are formed by the intersection of two lines (the line containing A - B - F and the line containing D - B - C) and are non - adjacent, so they are vertical angles.

Answer:

Vertical angles
