Exercise 3 Page 91

Translations are done by adding or subtracting values from the x-coordinate if the figure is being moved left or right, and from the y-coordinate if the figure is being moved up or down.

Practice makes perfect

Let's start by plotting the given points and connecting them to draw our quadrilateral.

Translations are done by adding or subtracting values from the x-coordinate if the figure is being moved left or right, and from the y-coordinate if the figure is being moved up or down. We want to draw the image of our figure after a translation of 3 units to the left and 2 units down. So, we will subtract 3 from the x-coordinate and subtract 2 from the y-coordinate of each vertex.

Vertices of WXYZ (x-3,y-2) Vertices of W'X'Y'Z'
W(1,2) (1 - 3,2 - 2) W'(- 2,0)
X(1,4) (1 - 3,4 - 2) X'( - 2,2)
Y(4,4) (4 - 3,4 - 2) Y'(1,2)
Z(4,2) (4 - 3,2 - 2) Z'(1,0)
Let's do the translation!
