Recall:

Point, line, line segment and Ray:

point ●

A point is an exact position on a plane surface

line 

A line is a set of points in a straight path that extends in opposite directions without ending.

line segment 

A line segment is a part of a line between two end points.

Ray 

A ray is a part of a line that has one end point and extends in one direction without ending.

Try this

1. Tick (✔) the correct alternative

i. 

The shortest distance between the points C and D is shown by the segment CD ✔ / the curve CD

ii.
