The interior angles of an 18 sided polygon add up to 2880 degrees
What is the interior and exterior angles on a 20 sided shape?
Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
What do the angles add up to in a 20 sided shape?
The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What is the sum of the measures in degrees of the interior angles of an 18-sided polygon?
(18-2)*180 = 2880 degrees
