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

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