Mateo says a ray is straight and goes on forever in two directions. His statement is incorrect. 
 
One of the following should Mateo replace "a ray" with to make the statement correct.

Oblique lines are

A __________ is a part of a line that has one endpoint and continues on forever in one direction.

The two lines that never cross are called________ 

A line segment 

The point at which two rays of an angle or two or more-line segments meet in a plane figure or where three or more edges meet in a solid figure. The top point of a cone. 

A _________ is an endless flat surface

A straight path with points in a plane that continues without end in both directions. 

A path is not a point but a collection of points in a straight path. Hence, option d is eliminated.
Also, a line segment and a ray are both parts of a line where a line segment has fixed or definite ends on both sides whereas a ray has one end fixed and the other end extends infinitely.
Hence, options b & c are also eliminated.

_______ lines are lines that form 4 right (90 degree) angles.

The letter A labelled on the circle shows a _________.
