Question

If an object is reflected twice over parallel lines, and corresponding points of the original and final translation image are 30 centimeters apart, how far apart are the parallel lines?

Answer 1

7.5

Answer 2

i think..., cuz basically if you take one point, u reflect it it wil be 15 cm from where it was, reflect it again it will be 30 cm, so basically 15 cm apart bw parallel lines, so jsut divide the value by 2, and it gives u 7.5

Answer 3

that help?
