The answer depends on what you are summing: the lengths of sides, interior angle, exterior angles.
The sum of the interior angles is 360.
No, the interior angles of a triangle sum to 180o The interior angles of a quadrilateral sum to 360o.
The sum of the interior angles of a parallelogram is 360 degrees.
((2 x 5) - 4) x 90 ie 540o
Interior angles of a triangle have a sum of 180 degrees.
A square always has a sum of 360 degrees for the interior angles.
A rhombus is a quadrilateral, so the sum of its interior angles is 360o.
The sum of the four interior angles of a trapezoid is 360 degrees.
(number of sides-2)*180 = sum of the interior angles
The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.
Do you mean the sum of interior angles? If so then it's: (number of sides -2)*180 = sum of interior angles
