Creating A Parallel Line - Texas Instruments TI-NSPIRE Software Manual

Repositioning segments with midpoints
1. To reposition the segment after placing it on the work area, click the
Pointer tool (
2. Select the segment and drag it to a new location without changing
its orientation or length, or select one endpoint and drag it to a new
location.
If just an endpoint is moved and if the length of the segment
changes, then the midpoint is repositioned to remain at the middle
of the segment.

2. On the work area, click once on an existing line, segment, or axis.

4. When the dotted line is in the desired position, click again to anchor
it on the work area.
