u To construct an angle bisector
1. Draw a triangle and select two of its sides.
2. Perform the following operation:
4(Construct) – 5:Angle Bisector.
• This draws the bisector of the angle formed by the two sides of the triangle that you
selected.
Note
• You can perform an angle bisector construct operation while two of any of the following
objects (two of the same object or two different objects) are selected on the screen: line
segment, line, ray, vector, or one side of a polygon.
• If the two objects you select are intersecting, the angle bisector construct operation will
construct two angle bisectors.
u To construct a parallel
1. Draw a line segment, plot a point, and select the line and point.
