△LMN is the result of a reflection of ​ △XYZ ​ across the y-axis.

Which angle in the image corresponds to ∠X in the pre-image?

∠L
∠M
∠N

Answer 1

∠X in the pre-image will be equal to ∠L in the main image

Explanation:

△LMN is the result of a reflection of ​ △XYZ which means △LMN is the mirror image​ △XYZ

hence, the left of △XYZ will be equivalent to the right of △LMN and the right of △XYZ will be equivalent to the left of △LMN

Hence, ∠X in the pre-image will be equal to ∠L in the main image
