Can you describe in your own words the difference between a segment, line and ray? Also see the algebra view and observe the equations of the line b and ray c. The line segment a is represented in the algebra view as a = 2.83, where 2.83 is the length of the segment.

iii. Select Point Tool and click anywhere on the drawing point to plot three points A,B, C.
iv. Select Line through two points tool, click on point A and then point B.
v. Select Parallel Line tool, click on point C first. Then click on line AB. Now use the Move Tool and move points A, B and C. What do you observe? Describe it.
Next with Move Graphics view tool and move the drawing pad. Do the two lines ever meet?

|style="width: 50%;|Step 7 - Rotate a ray
Draw line segment AB of any length (Segment between two points tool).
Select the Ray Through two points tool, click on point A, then select another point C on the drawing pad as shown in the figure.
Select the Angle tool, as seen in the figure and click on points B, then A and finally C. You will see an angle measure. Click on the Move tool and move point C.
