Question

The dashed line triangle is a dialation of the solid line triangle,

whats the scale factor

Answer 1

@Zale101

Answer 2

Did you measure the length of the big and the small triangle and tried to compare?

Answer 3

is it 2?

Answer 4

we know for sure that the scale factor of the dilation is increased by some number (that we must find) but not reduced. The dashed line triangle is bigger obviously.

Answer 5

Yes, two

Answer 6

the length (that crosses the x-axis) seems to have 9 on the left side and 7 on the right side. That equals 16. On the other hand, the small triangle has 4 units on the left and 4 units on the right along the x-axis. So the length of the small triangle is 8.
8*2=16
So, the scale factor of the dilation is increased by a factor of 2.

alrighty thanks
