Answer:
A
Step-by-step explanation:
We know that ∠ ≅ ∠
because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠
and ∠
as they have different measures, so we'll have to find the measure of either ∠
or ∠
. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is
°, we know that
∠
°. Now, we know that ∠
≅ ∠
because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by
. Hope this helps!
