The interior angles in a quadrilateral (4 sided shape) add up to 360 degrees.
540 degrees total degrees in shape = (( 180 x number of sides of shape) - 360)
An equilateral triangle has 3 equal interior angles that add up to 180 degrees
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
0.036 degrees.
The whole shape has 540 degrees in it. To work out the amount of degrees in any shape - total degrees in shape = ((180 x number of sides of shape) - 360)
The number of degrees in any geometric shape is 180*(n-2) where n is equal to the number of side. Since an octagon has 8 sides, there would be 180*6 or 1080 degrees total in the entire shape.
If each angle is 90 degrees the shape is called a square.
Exterior degrees 360 Interior degrees 540
360 degrees
Assuming every interior angle is the same, and they're all 162 degrees, the shape would have 20 sides.
138
900o To find the degrees in a shape subtract the number of sides by 2 and multiply it by 180. This gives you the number of degrees in a shape
