**# 16 Dilation benchmark M. A. 7. 8**

# 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 :)

2
definition Dilation is a similarity transformation in which a figure is enlarged or reduced using a scale factor, without altering the center.

3
drawing & formula 8 A B C D E 2 8 D

4
create a question Ishiki dilated the triangle by a scale factor of 4. What is the area of the changed/dilated triangle? A B C D E 2 E 2 D 2 A B

5
**solution The area of the dilated triangle is 32 in2. SO! steps:**

8 x 8 = 64 ÷ 2 = 32 in2.
