Hey there, creative minds! Avery, Grace, and Mason need your help to draw the reflection of an octagon and a pentagon across a mirror line. Please draw both shapes on one side of the mirror line and then create their mirrored versions on the opposite side. Let's see how well you can mirror their creativity!

Answer explanation

To mirror the octagon and pentagon, draw them on one side of the mirror line. Then, replicate their shapes on the opposite side, ensuring each point is equidistant from the mirror line to create accurate reflections.
