Geometric transformations

The Transform menu—displayed by tapping

—provides numerous tools for you to perform

transformations on geometric objects in Plot view. You can

also define transformations in Symbolic view

Translation A translation is a transformation of a set of points that moves

each point the same distance in the same direction. T: (x,y) →

(x+a, y+b). You must create a vector to indicate the distance

and direction of the translation. You then choose the vector

and the object to be translated.

Suppose you want to

translate circle B at the right

down a little and to the right:

1. Ta p

and select

Vector.

2. Draw a vector in the

direction you want to

translate the circle and

of the same length as move you intend. (If you need help,

see “Vector” on page 156.)

3. Tap and select Translation.

4. Tap the vector and press

5. Tap the object to be

moved and press

The object is moved the

same length as the

vector and in the same

direction. The original

object is left in place.
