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.	Tap	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 E.
	5.	Tap the object to be
		moved and press
		E.

The object is moved the same length as the vector and in the same direction. The original object is left in place.
