# 16 Dilation benchmark M.A Use coordinate geometry to determine the change in size of a figure that is dilated by a scale factor created by :)
definition Dilation is a similarity transformation in which a figure is enlarged or reduced using a scale factor, without altering the center.
drawing & formula D 8 8 AB C D E 2 2 8
create a question Ishiki dilated the triangle by a scale factor of 4. What is the area of the changed/dilated triangle? AB D E 2 2 AB C D E 2 2
solution steps: SO! 8 x 8 = 64 ÷ 2 = 32 in 2. The area of the dilated triangle is 32 in 2.
credits I would like to give thanks to Mr. Imamura for teaching us MATH! :) I would like thank Rebecca for letting me use her last name. :) I would like to thank Gelaney & James for approving my POWERPOINT! :) I would like to thank
