4 angles are formed
21 - including one of 360 degrees.
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.
Four of them.
If AB is a perpendicular bisector of CD then four 90 degreee angles are formed.
It has no angles because circles are not common shapes. Well they're common but they don't have ANY sides, angles, OR CORNERS!
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.
Two pairs of adjacent angles are formed when two lines intersect each other.
A line segment has two endpoints
Yes and no. The obvious is that they are both angles, but they are different from how many degrees they are.
In geometry, a line has no endpoints. If you are referring to a non-geometry application, a line has 2 endpoints.
An angle has two endpoints and a single vertex.
10 rays can meet in 45 vertices. At each such vertex there will be 4 angles which makes 180 angles in all.
There are 66 angles formed by 12 distinct rays with a common endpoint. The first ray by itself doesn't make an angle, the second ray makes 11 distinct angles, the third ray makes 10, the fourth 9, the fifth - 8, the sixth - 7, the seventh-6, the eighth - 5, the ninth- 4, the tenth - 3, the eleventh - 2, and the twelfth - 1 (it makes an angle with the first ray).
Four opposite equal angles are formed when 2 lines intersect each other
