1&2
1&3
1&7
4&5

Answer 1

Vertical angles are a pair of angles that are opposite each other and formed by the intersection of two lines. The angles are congruent, meaning they have the same measure. The set of vertical angles in the given options is 4&5.

Step-by-step explanation:

Vertical angles are a pair of angles that are opposite each other and formed by the intersection of two lines. The angles are congruent, meaning they have the same measure. In the given options, the set of vertical angles is 4&5, since angles 4 and 5 are opposite each other.

Answer 2

see explanation

Step-by-step explanation:

When 2 lines intersect to make an X, angles on opposite sides of the X are called vertical angles , and they are congruent (equal )

From the given diagram there are 4 pairs of vertical angles.

∠ 1 & ∠ 3 , ∠ 2 & ∠ 4 , ∠ 5 & ∠ 7 , ∠ 6 & ∠ 8
