Is triangle ABC = triangle DEF by HL? explain

Answer 1

No, triangle ABC is not equal to triangle DEF by HL. HL is a theorem that states that if two triangles have two sides that are equal in length and the included angle between them is also equal, then the two triangles are congruent. In this case, triangle ABC and triangle DEF do not have two sides that are equal in length and the included angle between them is not equal, so they are not congruent.
