Question

What’s the solution? How do you do this?

Answer 1

Not congruent.

Explanation:

We can solve this by checking if all of the angles inside the triangle are congruent. We can first check the angles inside ΔSPY.

180°-64°-28°= 88°.

For the triangles to be congruent, all of the matching angles must be the same. This means that for example, ∠A and ∠S have to be the same.

However, we derived that ∠S=88° and ∠A= 78°. This means that the triangles are not congruent.
