ing a Matrix or Vector (General Tran
s
form)
General Transform lets you input a matrix and/or vector to transform a figure. The result of
the transformation is drawn as a separate figure. For example, if you transform line segment
AB, the line segment A’B’ will be drawn.
You can perform the following types of transformations with General Transform.
• Matrix Transformation:
x
-axis/
y
-axis symmetry, rotation, enlargement, reduction, etc.
• Vector Transformation: Vertical and horizontal parallel displacement
I
General Tran
s
form Example
In this example draw triangle ABC and then draw triangle A’B’C’, which is symmetrical
to ABC about the
x
-axis. Next, we will draw triangle A’’B’’C’’ by performing a parallel
displacement on triangle A’B’C’ of 1 unit along the
x
- and
y
-axis.
S
To dilate a line
s
egment toward a
s
pecified center point
(1) Draw a line segment, and then select it.
(2) Tap [Draw], [Construct], and then [Dilation].
• This highlights the dilation button on the toolbar.
(3) Tap the center of dilation.
• This displays the Dilation dialog box.
(4) Specify the dilation scale factor.
(5)
Tap
[OK].
