(2, 4) and (6, 6)
(2, 4) and (6, 6)
(–2, 4) and (6, –6)
(2, –1) and (–3, 3)
2.
Given a scale factor of onehalf , find the coordinates for the dilation of the triangle with vertices at (0, 0), (0, 2), and (4, 0).
(0, 0), (0, 4), (8, 0)
(0, 0), (0, 1), (2, 0)
(onehalf,onehalf), (onehalf, 1), (2, onehalf)
(2, 2), (2, 4), (8, 2)
3.
The dashed figure is a dilation of the original figure. Find the scale factor. Classify the dilation as an enlargement or a reduction.
dashed figure dilation
2, enlargement
onethird , reduction
onehalf , reduction
3, enlargement

2 (2, 2), (2, 4), (8, 2)
3 2, enlargement
4 onehalf

1. (C) don't lose track of the signs
2. (B) just multiply coordinates by scale factor
