Question

the triangle shown in the diagram is going to be dilated by a scale factor of $\frac{1}{3}$. what is the length of the new side that corresponds to side ab? a 1 b 3 c 9 d $\frac{1}{3}$

Explanation:

Step1: Find length of AB

Point A is at (1,1), point B is at (4,1). The distance between them (length of AB) is $4 - 1 = 3$.

Step2: Apply dilation scale factor

Dilation scale factor is $\frac{1}{3}$. New length = original length × scale factor = $3\times\frac{1}{3}=1$.
