Exploring with Construction Tools

To add a construction, tap Tools , select Construction, and select the type of construction, such as Parallel. (In the Graphs application, go to Geometry > Construction > Parallel.)

While a construction is in progress, a tool appears in the application Toolbar (for example, Parallel ). To cancel, tap the X on the tool.

Construction Type	Description
Midpoint	Bisects a segment or sets a midpoint between any two points. The points can be on a single object, on separate objects or on the work area.
Parallel Line	Creates a parallel line with respect to any existing line. The existing line can be a Graphs axis or any side of a triangle, square, rectangle or polygon.
Perpendicular Line	Creates a line that is perpendicular to a reference line. The reference can be an axis, an existing line, a segment or one side of a triangle, rectangle or polygon.
Perpendicular Bisector	Creates a perpendicular bisector on a segment, on one side of a triangle, rectangle or polygon or between any two points.
Angle Bisector	Creates an angle bisector. The points of the angle can be on existing objects, or they can be locations on the work area.
Locus	Lets you explore the range of motion of one object with respect to another object as constrained by a shared point.
Compass	Operates similarly to a geometric compass used for drawing circles on paper.
