There could be none, there could be 5.
five lines of symmetry :)

any regular pentagon has five lines of symmetry.
What is a nonagram? A nine pointed star, perhaps. In any case, a general nonagram, like a general (ie non regular) polygram(!) has NO lines of symmetry.
five, if it's a regular pentagon.

If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.
the shape has 1 side of symmetry

five do the math But only if it is a 5-pointed star, not a 6-pointed star (like the star of David, for example). So doing the math requires counting the number of points in the star before getting to the put downs!
