How many lines of symmetry does a original 9 sided shape have

The interior angles of a 9 sided nonagon add up to 1260 degrees and its exterior angles add up to 360 degrees

360/9 = 40 degrees

A 9 sided shape that how many a nonagon has.

No, a nonagon is a 9-sided shape.

to calculate this, you must find out how many triangles you can draw in to the shape. do this by picking an angle. draw a line to all of the other angles. (for a 12 sided, there would be 9, subtract 3 from any shape to see.) mutiply the number of triangles by 180 degrees. this should be the degrees of the shape. for a 12 sider, the answer would be 1620 degrees.
