Identify lines of symmetry

Topic:
Symmetry
Given a regular pentagon ABCDE, draw the lines of symmetry.
  1. First, draw the pentagon and label the vertices.
  2. Extend a line from vertex A to the midpoint of the opposite side.
  3. Now move to the next vertex, B, and extend a line to the midpoint of the opposite side.
  4. Continue around to each vertex, extending a line from the vertex to the midpoint of the opposing line segment.
