Measuring and Transforming Geometric Objects

Measuring Objects

1.

Tap Tools , select Measurement, and select the type of measurement, such as Length. (In the Graphs application, go to Geometry > Measurement > Length.)

2.

Tap the object you want to measure.

Measurement Type	Use to Measure...
Length	• Length of a segment, circle arc, or vector • Distance Between Two Points, a Point and a Line, or a Point and a Circle • Circumference of a Circle or Ellipse or the Perimeter of a Polygon, Rectangle, or Triangle • A side of a triangle, rectangle, or polygon. You must tap two points to measure a side. Tapping the side measures the entire length of the object's perimeter.
Area	Area of a Circle, Ellipse, Polygon, Rectangle, or Triangle
Slope	Slope of a Line, Ray, Segment, or Vector
Angle	Angles in the range from 0° to 180° (0 radians to π radians in the Graphs application)
Directed Angle	Directed angles in the range from 0° to 360° (0 radians to 2π radians) and from -360° to 0° (-2π radians to 0 radians).

Transforming Objects

1.

Tap Tools , select Transformation, and select the type of transformation, such as Symmetry. (In the Graphs application, go to Geometry > Transformation > Symmetry.)

2.

Tap the object you want to transform.

3.

Tap a location, existing point, or other object to create the transformation.
