Exercise 3 Page 457

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.

P'(6,5), Q'(11,3), R'(3,11)

Practice makes perfect

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

polygon

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 6 units right and 5 units up. Therefore, we will add 6 to the x-coordinate and add 5 to the y-coordinate of each vertex.

Vertices of PQR (x+6,y+5) Vertices of P'Q'R'
P(0,0) (0 + 6,0 + 5) P'(6,5)
Q(5,- 2) (5 + 6,- 2 + 5) Q'(11,3)
R(- 3,6) (- 3 + 6,6 + 5) R'(3,11)
Let's do the translation!
