21 - including one of 360 degrees.
10 rays can meet in 45 vertices. At each such vertex there will be 4 angles which makes 180 angles in all.

Eight angles are formed - four for each line that the transversal cuts through. 2*4=8. Hope this helps!
Six angles.
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.
two endpoints

Two pairs of opposite equal angles are formed
A line segment has two endpoints
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.
