Question

Refer to the diagram above. Identify each angle pair as adjacent, vertical or neither.

Angle 2 and 5
Angle 4 and 6
Angle 3 and 4
Angle 1 and 4

Answer 1

2 and 5= vertical

4 and 6= neither

3 and 4= adjacent

1 and 4= vertical

Explanation:

Answer 2

Angles 2 and 5 are vertical angles.
Angles 4 and 6 are neither.
Angles 3 and 4 are adjacent angles.
Angles 1 and 4 are vertical angles.

∠2 and ∠5 are vertical angles because they share only a vertex.
∠3 and ∠4 are adjacent angles because they share a side and a vertex.
∠1 and ∠4 are vertical angles because they share only a vertex.
