Question

triangle a and triangle b are similar triangles.
triangle a has sides 3, 4, 2. triangle b has sides 6, 8, 4.
what is the scale factor from triangle a to triangle b?
enter answer

Explanation:

Step1: Pick corresponding sides

Take side of A=2, side of B=4

Step2: Calculate scale factor

$\text{Scale factor} = \frac{\text{Length of B side}}{\text{Length of A side}} = \frac{4}{2} = 2$
(Verify with other sides: $\frac{6}{3}=2$, $\frac{8}{4}=2$)
