An angle is formed when two rays meet.
an angle
CAB
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
A right angle (90 degrees).

An angle.
A real image in produced by the actual intersection of the reflected rays . Whereas a virtual image is formed when the reflected rays meet after they are produced backwards.
Depending on the location of the intersection, there are many things though could be formed, but to pick commons, it could form a +, T, L
180 degrees because opposite rays form a straight line.
2 is the minimum number of light rays required to locate the image (of a point object) formed by a lens. First find the path of rays after refraction and then their point of intersection gives the location of the image.

That's called an angle.
