Question

If a ray lays in a plane, how many points of the ray are also in the plane?

Answer choices
a) all of the points
b) two points
c) three points
d) zero points

Answer 1

Option: a is the correct answer.

a) all of the points

Explanation:

We know that if a figure or a line lie in a plane then all the points that lie on that figure also lie in the same plane.

i.e. the points are said to be co-planar points.

Ray--

Ray is a line which originates at a point and it goes to infinity from the other end.

Hence, If a ray lays in a plane, then all the points that are on that ray also lie in the same plane.
