180 degrees
An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. The internal angles of any regular polygon with 5 or more sides will be obtuse.
The internal angles add to 180 degrees.
The internal angles add up to 360 degrees. If the trapezium has its base parallel to the top then the internal angles on the left of the parallel lines add to 180 degrees, the angles on the right add to 180 degrees.
The sum of the internal angles of any regular polygon is (n - 2) x 180 degrees. Since a triacontakaihexagon has 36 sides, the sum of the internal angles of a triacontakaihexagon has a sum of internal angles of (36 - 2) x 180 = 6120 degrees.
I believe that regular shapes will only tessellate if the sum of their internal angles is a multiple of 180.
The internal angles of a triangle always add up to 180 degrees.
No, the internal angles of a triangle add up to 180 degrees
It can be proven that the sum of all the internal angles of a polygon with n sides is (n-2)*180 degrees. In the case of a square, n = 4 and so the angles sum to (4-2)*180 = 2*180 = 360 degrees.
All triangles have internal angles summing to 180 degrees. An equilateral triangle has three equal angles, each of which is 180/3 = 60 degrees.
The sum of the internal angles is 180*(11 - 2) = 180*9 = 1620 degrees. The sum of the external angles is 360 degrees - irrespective of the number of sides.
