Perpendicular Line
The
Perpendicular Line
tool creates a line passing through a point and perpendicular to a selected
linear object (line, segment, ray, vector, or side of a polygon).
Creating a perpendicular line
1.
Select
Perpendicular Line
from the
Construct
toolbox.
2.
Point to the line, segment, ray, vector, or side of a
polygon that will be perpendicular to the
constructed line, and click to select.
Select a linear object.
3.
Click to create or select the point through which
the perpendicular line will pass.
Note:
The order of steps 2 and 3 may be reversed.
Select a point.
A dependent line is created.
Modifying a perpendicular line
Move a perpendicular line by dragging the point through
which it passes.
The line cannot be altered directly because it is, by
definition, a dependent object.
Example
Select a linear object.
Create a point, and the
perpendicular line is constructed.
