Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees so all together 2160
Providing that it's a regular 27 sided polygon then the interior angles add up to 4500 degrees and each interior measures 166o40'0''
Exterior angles add up to 360 degrees Interior angles add up to 900 degrees
Exterior angles add up to 360 degrees Interior angles add up to 17,640 degrees
Interior angles = 1080 degrees Exterior angles = 360 degrees
The exterior angles of a 15 sided shape add up to 360 degrees
The interior angles of a 24 sided shape add up to 3960 degrees
The total sum of angles of an n-sided shape is (n-2)x180o Hence, the angles in a five sided shape add up to (5-2)x180o = 3 x 180o = 540o
There is no three-sided shape with two obtuse angles, because the three interior angles of a three-sided shape, which is a triangle, add up to 180 degrees, and two obtuse angles would be over 180 degrees.
