Question

To prove "alternate interior angles" are equal, we need atleast two transversal lines.

• A. True
• B. False

Answer 1

Answer: (B)

False
When two lines are crossed by another line (transversal line), Alternate Interior Angle are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.

According to the definition, we can prove that "Alternate Interior Angle" are equal even if we have only one transversal line cutting two parallel lines.
