What are the characteristics of polygons?

A polygon is any plane figure bounded only by straight lines. A triangle is therefore a polygon with three sides and a pentagon is a polygon with five sides. A convex polygon has no interior angle greater than 180° . A re-entrant polygon has at least one interior angle greater than 180° . A regular polygon has all its sides and angles equal. The sum of the interior angles of a polygon is 2n - 4 right angles (n is the number of sides). The sum of the exterior angles of a convex polygon is 360° .

Does a parallelogram have right angles?

a parallelogram is a 4 sided polygon with two pair of parallel sides. So squares and rectangles are parallelograms since they have 2 pair of parallel sides and yes they have right angles, BUT most parallelograms do not have right angles. So the answer is it may have them, but does not need to have them
