Asemmisa {{asɛmmisaAhyɛnsode}}
1.

When the scale factor is greater than one it is called a(n) .

Asemmisa {{asɛmmisaAhyɛnsode}}
2.

The dilation rule :

(x,y)--------->(5x, 5y)

means that you transform the original points of a figure by

:

Asemmisa {{asɛmmisaAhyɛnsode}}
6.

When you reduce a figure the angles get smaller.

7.

What is the center of dilation of this transformation?

Asemmisa {{asɛmmisaAhyɛnsode}}
8.

What is the scale factor of this dilation:

Write it in the format (x,y)--------->(kx, ky); where k is the scale factor.
