Which of these triangle pairs can be mapped to each other using a single reflection?​
kondor19780726 [428]

Answer:

Second triangle pair

Step-by-step explanation:

In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.
