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.
