- - - - - - - - -_E,_F, ~ Triangles EFGand JKLare congruent, where and G correspond to J, K, and L, respectively. The 45° measure of angle E is and the measure of 20° angle F is. What is the measure of angle J? 20°
Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice B is correct. It’s given that triangles EFG and JKL are congruent such that angle E corresponds to angle J. Corresponding angles of congruent triangles are congruent, so angle E and angle J must be congruent. Therefore, if the 45° 45° measure of angle E is , then the measure of angle J is also . Choice A is incorrect. This is the measure of angle K, not angle J. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
