We are given two figures.
We need to name the line of reflection for each of the figure.
Line of reflection is a line that divide a figure in two half identical (similar) figures.
In order words, a line of reflection is a line that divide a figure into two mirror images of the figure.
For the first figure lines m and n are intersecting each other. The segments up and down are mirror images of each other for both lines.
Therefore, for first figure both line m and n are lines of reflection.
For second figure (figure of heart) is cut by line P into two identical figure ( imrror images).
Therefore, for second figure line of reflection is p.
