Use the formula 180*(n-2), 'n' being the number of sides in the figure. So that's 180*(12-2)
180*10
1800
That'll work with any polygon ^_^
The sum of the interior angles is 360.
(number of sides-2)*180 = sum of the interior angles
The sum of the four interior angles of a trapezoid is 360 degrees.
The sum of the interior angles of a decagon is 1440 degrees The sum of the interior angles of a triangle is 180 degreesThe difference in the sum of the interior angles of a decagon compared to a triangle = 1440 degrees minus 180 degrees = 1260 degrees
-- The sum of the four exterior angles is 360 degrees. -- The sum of the four interior angles is also 360 degrees. -- So the sum of all the interior and exterior angles is 720 degrees.
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.
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
The interior angles sum to 180*(N - 2) degrees.The interior angles sum to 180*(N - 2) degrees.The interior angles sum to 180*(N - 2) degrees.The interior angles sum to 180*(N - 2) degrees.
The sum of the interior angles of ANY triangle is 180 degrees.
