Question 18359
 how many lines of symmetry does a pentagon have?
and how many does a rhombus have ?

 For pentagon the perpendicular bisector of each side forms a symmetry.
 (reflection A<-->B, C<-->D , E fixed)

     A*-----*B
         |
         |
  C      |     D
         |
         E

 So,there are 5 lines of symmetry. (cannot draw proper diagram here)

 For rhombus,the two diagonal lines are lines of symmetry.
