EVERY POINT on the figure
undergoes the SAME transformation
Description = a verbal expression
Describe each translation using words like
units, up, down, left, and right.

Question 1:
If a point on the coordinate plane moves horizontally, which
coordinate changes? The x or y coordinate?
Question 2 :
If a point on the coordinate plane moves vertically, which
coordinate changes? The x or y coordinate?

Mapping Translation
(x,y) (x+2, y-7)
Example 1: What is the image of the points in figure
ABC (x,y) (x-7,y-3) ?
A (3,1), B (4,4), C (1,2)
Example 2: What is the images of the points
in figure ABC (x,y) (x+4,y+1)?
A (-3,-1), B (-4,-4), C (-1,-2)
S.25
ex)
A`(-4,-2),B`(-3,1),C`(-6,-1)
A`(1,0),B`(0,-3),C`(3,-1)

Example 3: What is the images of the points
in figure EFG (x,y) (x+4,y+1)?
E (-3,-1), F (-4,-4), G (-1,-2)

T(2,-3)
For the following examples, use the following coordinate points to
translate figure ABC.
A (-1,6) B (2,4) C (-3,-2)
Example 1: T(2,3) Example 2: T(1,-4)

Important Aspects of a Translation:
1. A translation occurs when a figure slides across a coordinate plane.
2. If a figure is translated horizontally (left or right) the x coordinate
changes.
3. If a figure is translated vertically (up or down) the y coordinate
changes.
4. A translated figure will never change in size or shape but only in its
location.
