construct various types of geometric objects, such as a perpendicular bisector, parallel,
angle bisector, etc.
u To construct a perpendicular bisector
1. Draw a line segment and select it.
2. Perform the following operation:
4(Construct) – 1:Perp Bisector.
• This will draw the perpendicular bisector of the line segment you selected.
Note
You can perform a perpendicular bisector construct operation while a single line segment,
one side of a polygon, or two points are selected on the screen.
u To construct a perpendicular
1. Draw a line segment, plot a point, and select the line and point.
2. Perform the following operation:
4(Construct) – 2:Perpendicular.
• This will draw a perpendicular to the selected line segment and passes through the
selected point.
