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.

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.

If Triangle Y is congruent to triangle X and Triangle Y is congruent to triangle Z, hence Triangles X and Z are congruent.

Congruent triangles

Two triangles are said to be congruent if they have the same shape and their corresponding sides are congruent. Hence all the three sides and three angles are congruent.

If Triangle Y is congruent to triangle X and Triangle Y is congruent to triangle Z. Therefore:
