How many degrees are in the measure of an interior angles of a regular seven sided polygon? A formula for this question is that the total measure of the interior angles of a polygon is 180 degrees multiplied by 2 less than the number of sides. For a seven sided polyg â¦ on, this formula yields 180 X 5 = 900 degrees.
How many angles does a heptagon have? Credit: karlhorton CC-BY 2.0. In a regular heptagon, one in which all sides and angles are equal to each other, each interior angle is equal to approximately 128.57 degrees, with the sum of all interior angles being equal to 900 degrees. The area of a regular heptagon can be found by multiplying 3.63 by the length of one side squared.
