4. Next, let's add a column to the table that shows the area of triangle ABE at
each step. Perform the steps below.
(1) Draw a line segment that connects point A with apex E.
(2) Select line segment AB, line segment AE, and side BE.
(3) Tap # next to the measurement box.
This adds a column that shows the area of triangle ABE at each step.
(As can be seen, the area of triangle ABE does not change even when
point A moves.)
8-5 Using the Geometry Application with Other
Applications
You can display the Geometry application from within the eActivity or Main application. This feature allows
you to visualize the relationship between Algebra and Geometry. You can, for example, drag a figure from the
Geometry window to the eActivity window to see its corresponding mathematical expression.
Drag and Drop
When you open Geometry within another application, you can drag and drop information between the two
application windows. You can see an actual example (
Chapter 2 of this manual.
The information that appears when you drop a figure into another application depends on the figure you are
dragging. Many of the possible outcomes are listed in the table below.
Geometric Figure
Point
Line Segment, Infinite Line,
Ray
Vector
Circle, Arc
Ellipse
y

x
Function (

Two Lines
Polygon, or open polygon

Pairs of points related by a
transformation
*1 Support for drag and drop into a Geometry Link row in an eActivity. For details about a Geometry Link row,
see "Inserting a Geometry Link Row" on page 184.
Copy and Paste
In addition to drag and drop, you can also copy figures or columns from an animation table and paste them into
another application.
Drag and drop into another application transforms to:
Ordered pair
Linear equation
Ordered pair (head of vector, assuming the tail is at the origin)
Equation of a circle
Equation of an ellipse
Equation of the function
System of equations
Matrix containing each vertex point
Expression showing point relationship
