Question from anisha, a student:

how many lines of symmetry does a parallelogram have. A square and a rectangle are a
parallelogram too. so it is confusing?? pls help


A general parallelogram has no lines of symmetry. Some special ones (rhombus, rectangle, square) have lines of symmetry.

However, a parallelogram does have a crucial symmetry - the half-turn around the central point where they two diagonals intersect.
