A coplanar point are points that lie on the same line. An angle is the intersection of two noncollinear rays at a common endpoint. The rays are called sides and the common endpoint is called the vertex.


hope that helps

A ray is a part of a line with one endpoint and goes on and on in one direction... Parallel lines are lines that never intersect or cross one another. Perpendicular lines cross each other or intersect at right angles. An angle is two lines that meet at an endpoint called a vertex.
