A parallelogram has four sides. All four sided figures have a sum of the interior angle measures equal to 360°.
810 degrees
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.

The sum of the interior angles of a 14 sided polygon are 2160 degrees.
2880 degrees
2160 degrees
17,460 degrees

2340 degrees
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
