In triangles and , angles and each have measure and angles and each have measure . Which additional piece of information is sufficient to determine whether triangle is congruent to triangle ?
Explanation
Choice C is correct. Since angles and each have the same measure and angles and each have the same measure, triangles and are similar, where side corresponds to side . To determine whether two similar triangles are congruent, it is sufficient to determine whether one pair of corresponding sides are congruent. Therefore, to determine whether triangles and are congruent, it is sufficient to determine whether sides and have equal length. Thus, the lengths of and are sufficient to determine whether triangle is congruent to triangle .
Choice A is incorrect and may result from conceptual errors.
Choice B is incorrect and may result from conceptual errors.
Choice D is incorrect. The given information is sufficient to determine that triangles and are similar, but not whether they are congruent.
