Question

what is the scale factor if the triangle on the left is the original? 1/2 3/2 2 2/3

Explanation:

Step1: Identify corresponding side lengths

Assume we know a side - length of the original triangle and its corresponding side - length of the new triangle. Let's say the length of a side of the original triangle is \(a\) and the length of the corresponding side of the new triangle is \(b\). The scale factor \(k=\frac{b}{a}\). If we assume the side - length of the original triangle is \(3\) ft and the corresponding side - length of the new triangle is \(2\) ft, then \(k = \frac{2}{3}\).

Answer:

D. \(2/3\)
