Question

A-32-10A. 20-C?LBDIn the similaritytransformation of AABCEto AEDF, AABC was dilated bya scale factor of [?], reflectedacross the [ ], and movedthrough the translation [ ].B. 1/23 4F 5 Find the answer to all three missing boxes

Answer 1

To find the scale factor use the next formula:

`sf=\frac{dimension\text{ }new\text{ }shape}{dimension\text{ }original\text{ }shape}`

Use dimension of corresponding sides AB and ED:

`sf=(2)/(4)=(1)/(2)`

Then, the scale factor is 1/2

___________

After the dilation the figure is reflected across the y-axis

_____________

Then, the triangle is translated one unit to the right and 3 units up [+1,+3] or [1,3]
