21(2o)/2 = 210 angles
tnx... dont know kung tama
If you mean all angles that meet at one point, it's 360° Ratty
360 degrees.
Six angles.
Depends on a concave what. There can be infinitely many right angles in concave shape that keeps going in and out before returning to its starting point.
Join all the corners to a point inside. For N sides that gives N triangles. Total angles = 180xN. Subtract off the angles at the chosen point (360 deg) to leave the angles at the corners totalling 180x(N-2).
if the rays have no common points, the answer is zero. if the rays all have the same end point, the answer is 21 -- counting only the acute angles.
It has no angles because circles are not common shapes. Well they're common but they don't have ANY sides, angles, OR CORNERS!
Yes and no. The obvious is that they are both angles, but they are different from how many degrees they are.

An oval has no exterior angles(or an infinite number depending on your point of view!)

Cape Horn is the southernmost point in the world, aside from Antarctica, has many landforms. There are mountains, channels, and fjords.
Six angles.
