Question

1. choose the correct answer.

congruent triangles are triangles in which their ______ angles and sides are congruent.

corresponding

included

relative

nonincluded

Explanation:

Congruent triangles have all corresponding parts (angles and sides) equal. "Included" refers to angles between two sides in a specific context (like SAS - Side - Angle - Side), which is not the general case for congruent triangles. "Relative" is too vague. "Non - included" is also a term related to specific triangle congruence criteria (like SSA, which is not a valid congruence criterion in general). The key concept for congruent triangles is that their corresponding angles and sides are congruent.

Answer:

corresponding
