Match the term with the definition. match term definition circle a) a figure consisting of two rays with the same endpoint vertex b) a point where two or more rays or "arms" of an angle meet angle c) a location, has no size ray d) the portion of a line that starts at one point and goes off in a particular direction to infinity point e) the set of all points in a plane that are a given distance from a point

A ray is a part of a line that has one endpoint but the other end continuous in the other direction infinitely. So one pair would be: RAY - the portion of a line that starts at one point and goes off in a particular direction to infinity.

A point is just a location in a line or plane. It has not value and is not measured. This means that there are no dimensions considered in a point. So another pair would be: POINT -  a location, has no size 

An angle is 2 rays or lines that share a common endpoint called the vertex. The symbol of an angle is ∠. So another pair would be: ANGLE - a figure consisting of two rays with the same endpoint.

Like mentioned above, a vertex is the endpoint where two figures meet. In an angle, the vertex is the point where the two rays or figures meet. So for this pair it would be: VERTEX - a point where two or more rays or "arms" of an angle meet

This would then leave CIRCLE - the set of all points in a plane that are a given distance from a point. To be more specific, a circle is made when all points in the same plane lie at a distance that is equal to the CENTER point.
