### DO NOW 12.19.13

DILATIONS Find the area.enlarge or reduce the size of a figure. We can manipulate ordered pairs based on the dilation given.

DILATIONS greater than 1 will make a figure larger, while dilations less than one will make a figure smaller. Closure

1. You are asked to find the area of a 3x3 square (shown). Find the area.

You are asked to dilate the square (DILATION of 2). Will the square be larger or smaller than the original?

Draw the new square in the space to the right.

How does the area compare to the original? Will this work for any figure?

Area: 36 square units

Area: 9 square units

DILATIONS Find the area.enlarge or reduce the size of a figure. We can manipulate ordered pairs based on the dilation given.

DILATIONS greater than 1 will make a figure larger, while dilations less than one will make a figure smaller. Closure
