The answer depends on whether any of the points are collinear: that is, whether they lie on the same line. No matter how many points you have, if they are all collinear you will have only one ray.
If you have N points, the maximum number of rays is attained when no three of them are collinear. This number is N*(N-1)/2.
the vertex is the point where two rays begin and form and angle
An angle is formed when two rays begin at a common point. The common point is called the vertex of the angle.
angle
The vertex of an angle is the point at which the two rays that form the angle meet.opposite point
common point of two rays or lines, note: rays and lines are the same thing!!
infinite
It is possible to construct an infinite number of lines through any line at a given point. You will not be able to physically draw them, but a filled in circle will all have rays that intersect the line at the same point.
Infinitely many. There an infinite number of points on a line and each point can be an end point of two rays.
wew
To locate an image, only two non-parallel rays are needed. These rays intersect at the image point, which is the point where the image is formed.

It depends on what information about the rays is given. If all you have is two rays drawn on a sheet of paper then you need to measure the angle using a protractor. If their equations are given - in standard or vector form, then there are formulae that will enable you to work out the angle between them.
Yes, numerous rays can have the same point.
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.
The point at which the rays of an angle intersect is the vertex.
The point where light rays meet is called the focal point.
Number of rays subtracted by one and adding all previous numbers. Example : number of rays : 13 13-1=12 1+2+3+4+5+6+7+8+9+10+11+12=78 there are 78 angles in 13 rays. Or if you were given a sequence pattern. Number of rays. Number of angles. 1-0 2-1 3-3 4-6 5-10 6-? 7-? Get number of rays minus 1 then add it to the previous number of angles. 6-1=5 5 + 10 (number of angles in 5 rays) = 15 7-1=6 6 + 15 (number of angles in 6 rays) = 21 -werty-sama
