A translation maps ∠E onto ∠A, is ∠B ≅ ∠D
The test got it right, but you can just use the triangle sum theorem to know that when you have two angles of a triangle, you automatically know the third angle is the same.
What is the sum theorem?
The triangle sum theorem, also known as the triangle angle sum theorem or angle sum theorem, is a mathematical statement about the three interior angles of a triangle. The theorem states that the sum of the three interior angles of any triangle will always add up to 180 degrees.
We can also see this in the AA similarity postulate as all you need to know is two angles to know if it is a similar triangle.
