DO NOW 12.19.131. You are asked to find the area of a 3x3 square (shown). Find the area.
2. You are asked to dilate the square (DILATION of 2). Will the square be larger or smaller than the original?
3. Draw the new square in the space to the right.
4. How does the area compare to the original? Will this work for any figure?
Area: 9 square units
Area: 36 square units
Independent Practice
DILATIONS 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
Write ordered pairs for the each point shown.Apply the factor of the dilation to the ordered pairs.Identify and plot the new points, then sketch the figure.
Identify the points given on a coordinate plane.
