Ethan created three triangles: triangle X, triangle Y, and triangle Z. If Triangle Y is congruent to triangle X and Triangle Y is congruent to triangle Z, which must also be true? The triangles are equilateral. The triangles are right triangles. Triangles X and Z are congruent. Triangles X, Y, and Z share one or more vertices.

The triangles are equilateral

Step-by-step explanation:

If Triangle Y is congruent to both angles pretty sure they would form up to 180degree because one angle would be 60degree due to it saying it is congruent to both of the x and z angles.
