Step-by-step explanation:
Each transversal crossing a line generates 2 pairs of vertical angles and for 3 transversal crossing the same line it will be 3 x2 = 6 pairs (or 12 angles)
The number of the pairs of vertical angles is 6.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Each transversal crossing a line generates 2 pairs of vertical angles and for 3 transversals crossing the same line it will be 3 x 2 = 6 pairs.
Therefore, the number of pairs of vertical angles is 6.
