Draw a line with 3 distinct points on it. Label each with a different letter. how many different rays can you name using only the 3 given points?
A) 8
B) 6
C) 4
D) 2
4 answers
please help me!!
you know that it takes 2 points to define a ray, right
so, how many ways can you choose 2 points from 3?
3P2 = 3*2 = 6
That is, you can pick any point for the start of the ray,
then choose any of the others to indicate the direction.
But, if the points are A,B,C in that order, then
ray AC is the same as ray AB.
So that changes things, right? See what you can do with that.
