Question #10: Given triangle A is the pre image and B is the image, state the scale factor of the dilation from A to B. * 4 B 10 18 А 7.2 15

Sagot :

To find the acale factor we need to solve the following equation:

[tex]\begin{gathered} 18k=7.2 \\ k=\frac{7.2}{18} \\ k=0.4 \end{gathered}[/tex]

This comes from the fact that the biggest sides of both triangles have to be realted.

Therefore the dilation factor is 0.4.
