8 sides
4
The sum of all the interior angles of any octagon is 1080 degrees, so that means that each angle is 135 degrees. You can find the measure of all the interior angles of any ploygon by using this equation: (number of sides in the polygon subtracted by 2) all multiplied by 180.
10 sides.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.
heptagons have 7 sides
An octagon has 8 sides.
If you mean an octagon then it has 8 sides and 8 interior angles that add up to 1080 degrees.

a crescent has 19 sides
Mo such shape/thing as a 'polgon'. If you mean ' polygon'. The word 'polygon' means a 2-dimensional shape (--gon) of many sides (poly--). So the word 'polygon' mean an many sided shape. For a specific number of sides it becomes;- trigon ( triangle) 3 sides quadragon ( quadrilateral ) 4 sides pentagon 5 sides et seq.,
10 sides.
