sum interior angles = (number of sides - 2) × 180°= (8 - 2) × 180°= 1080°The sum of the interior angles of an octagon is 1080°In a regular octagon, divide by 8 for each angle = 135°.
Each interior angle = sum of angles/number of sides
The sum of each pair of interior and exterior angles of a polygon is always 180 degrees.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
Interior angles of a triangle have a sum of 180 degrees.
Sum of interior angles - 180 degree (each side 60 degree) Sum of exterior angles of a polygon - 360 degree
-- Measure, calculate, or somehow get the measure of each interior angle. -- Add them all up to get one number which is their sum. -- That one number is the sum of the interior angles.
It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle
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.
It depends how many sides the shape has. If n is the number of sides of the shape, then the interior angles sum to (n - 2) x 180o. The exterior angles of any shape sum to 360o.

The sum of the interior angles of a parallelogram is 360 degrees.
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
