Question

which angles are congruent to each other? ∠14 and ∠13 ∠14 and ∠16 ∠13 and ∠3 ∠5 and ∠2

Explanation:

Step1: Recall vertical - angle property

Vertical angles are congruent. When two lines intersect, the pairs of opposite angles formed are vertical angles.

Step2: Identify vertical - angle pairs

In the given figure, when two lines intersect, $\angle14$ and $\angle16$ are vertical angles.

Answer:

$\angle14$ and $\angle16$
