1. which correspondence accurately describes the two congruent triangles shown here?

triangleabe = trianglebcd
triangleaeb = trianglecbd
triangleeab = triangledbc
triangleabe = trianglecbd

60°

180°

30°

not enough information given

you : )

In the first image, the congruence can be written in three ways:

As you can see, among the given options, the correct answer is the last one:

Because, with this arrangement, all congruent parts are at their corresponding position, that is:

The other image is about an equilateral triangle, because it shows all sides congruent. From the definition of this triangle, it's deducted that all angles are equal, and we now that the sum of all internal angles in a triangle must sum 180°. That means that each angles measures 60°, because 60+60+60=180

Therefore, in the second image, the answer is 60°.

ok then what happened.
