Constructing Straight Objects

Sketchpad provides several different ways to construct straight objects.

· Use the Straightedge tool to construct a straight object using two points.

· Use the Segment, Ray, or Line command to construct a straight object using two selected points.

· Use the Perpendicular Line or Parallel Line command to construct a line parallel or perpendicular to a selected straight object.

· Use the Angle Bisector command to construct the ray bisecting the angle formed by three selected points.
