Identify lines of symmetry

Given a regular pentagon [i]ABCDE[/i], draw the lines of symmetry.

[list=1] [*]First, draw the pentagon and label the vertices. [*]Extend a line from vertex [i]A[/i] to the midpoint of the opposite side. [*]Now move to the next vertex, [i]B[/i], and extend a line to the midpoint of the opposite side. [*]Continue around to each vertex, extending a line from the vertex to the midpoint of the opposing line segment. [/list]
