is △YXZ ≅△AZX a SSS
In order to determine if two triangles are congruent by SSS (Side-Side-Side) criterion, we need to show that all three corresponding pairs of sides are congruent.
Given that △YXZ and △AZX, we need to compare the lengths of the sides.
Unfortunately, we are not provided with any information about the side lengths of the triangles, so we cannot determine if △YXZ ≅△AZX using the SSS criterion.
