Answer:
A
Step-by-step explanation:
When doing those statements, the shapes are labelled as a combination of the labels of their angles. The larger trapezoid has angles A, B, C, and D. The smaller one has E, F, G, and H.
When you write statements about multiple shapes, especially when comparing them to one another, you want to make sure those angle labels stay in the SAME ORDER.
Let's say we flipped the little trapezoid upside down. Now it's in the same position as the big one. Then, you'd label them in the order of their congruent angles. A is congruent to E, B is congruent to F, and so on and so forth.
Luckily for us, this stays in alphabetical order. So, ABCD ≅ EFGH.
