### Construction of Line Segments

The different possible ways to generate line segments are:

Figure 40: Characterizations for line construction

Exercise (CREATE LINE PP): Generate a line segment with starting point (30,140) and end point (90,140) .
Solution: Click the icons and enter the values corresponding respectively to P1 and P2 in the command line.

Figure: CREATE LINE PP

Exercise (CREATE LINE PRLE): Beneath the previous line, construct a parallel line segment at a distance of -20 .
Solution: Click the icons and select the line segment, then enter the distance DST on the displayed numeric keypad; last position the point for the optional parameter SEL (selection) under the parallel line segment.

Figure: CREATE LINE PRLE

Additional exercise: Now construct a rectangle by connecting the end points of the two line segments.
Solution: Use the command CREATE LINE PP.

Figure 43: Rectangle

Exercise (CREATE LINE PA): Construct a rectangle with length= 70 and height= 30
Solution: Generate a point, enter an angle value ANG of 90 and a segment length L of 30 . Proceed in the same way for the subsequent line segments, except for selecting the end point of the previous segment for the mandatory parameter P. (The last line segment may alternatively be constructed with the command CREATE LINE PP.)
