Question

triangle a is a scaled copy of triangle b. the scale factor from a to b is \\(\frac{1}{4}\\). what is the scale factor from b to a?
a \\(\frac{1}{2}\\)
b \\(\frac{1}{4}\\)
c 2
d 4

Explanation:

Step1: Understand scale factor inverse

If the scale factor from A to B is \( \frac{1}{4} \), then the scale factor from B to A is the reciprocal.

Step2: Calculate reciprocal

The reciprocal of \( \frac{1}{4} \) is \( \frac{1}{\frac{1}{4}} = 4 \).

Answer:

D. 4
