Casio FXCP400 ABC, Example:, Select this:, • Three points, 1. Draw the triangle, Angle between two lines, Area of selected figure, Chapter 8: Geometry Application

Inserting Text Strings into the Screen

You can insert text strings into the screen while working on the Geometry application window. To do so, tap [Text] on the [Draw] menu. On the dialog box that appears, input the text you want, and then tap [OK].

Attaching an Angle Measurement to a Figure

The measurement of an angle formed by two sides of a figure can be attached to the figure as shown here. To do so, tap [Attached Angle] on the [Draw] menu.

uTo attach an angle measurement to a figureExample: To attach the measurement of angle A in triangleABC1. Draw the triangle.2. Tap G. Next, tap side AB and then side AC to select them.3.Tap [Draw] and then [Attached Angle].• This attaches the angle measurement to the figure.

Tip: The two sides of the figure actually form four angles in the illustration shown here. After attaching an angle measurement using the [Attached Angle] command, you can drag it to the position of any one of the other three angles as shown in the example below.

Example: To drag the angle measurement attached to interior angle A of triangle ABC to its exterior supplementary angle

Displaying the Measurements of a Figure

You can display measurements on the Geometry application window. The measurements change dynamically as you manipulate the figure.

uTo display a measurement of a figure

1. What you should select (point, line, figure, etc.) depends on the type of measurement you want to display.

To display this type of measurement:	Select this:
Angle between two lines	Two lines (Any two of the following: line segment,
	infinite line, ray, or vector, one side of a polygon)
Supplementary angle of extended lines
Area of selected figure	• All the sides or all the apexes of a polygon
	• The circumference of a circle, ellipse, or arc
Circumference or perimeter of selected figure
	• Three points
