Question

polygons rkwmh and rkwmh are shown on the grid. rkwmh is copied on a piece of patty paper and is reflected over a line. which line of reflection, 1, 2, 3, or 4, results in rkwmh mapping on top of rkwmh? line was used as the line of reflection.

Explanation:

Step1: Recall reflection property

In a reflection, each point of the original polygon has a corresponding point on the reflected polygon that is equidistant from the line of reflection.

Step2: Analyze distances

By observing the positions of the vertices of polygon $RKW MH$ and $R'K'W'M'H'$ relative to the given lines, we can see that for each vertex of $RKW MH$, its distance to line 3 is the same as the distance of the corresponding vertex of $R'K'W'M'H'$ to line 3.
