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.
