6. A triangle has sides measuring 6, 8, and 10 cm. Using a dilation factor of 0.75, what would the measurements of a second triangle be?

- 7.5 cm - 6 cm - 4.5 cm

4. Tori went to the eye doctor. He dilated her pupils to twice their normal size during the exam. If her pupils were 2 mm originally, what size were they after being dilated?

4 mm

5. Blueprints for the model of a new garage have a scale factor of 1 inch = 4 feet. If the garage is to be 18 feet long, what is the length of the model?

4.5 in

1. Match the coordinates to the points.

A : (3, 4) B : (-1, 5) C : (-6, -7) D : (0, -5) E : (4, 0) F : (6, -3)

3. Match the points to the coordinates.

M : (-5, -5) N : (5, -1)

2. Match the points to each area.

quadrant I : A quadrant II : B quadrant III : C quadrant IV : F on the x axis : E on the y axis : D

7. check answers Give the resulting coordinates if you were to reflect the point (2, 3) across the following lines.

x axis : (2, -3) y axis : (-2, 3) y = x : (3, 2) y = -x : (-2, -3)
