Question

Suppose you have two triangles. In triangleABC, AB = 4, BC = 5, and CA = 6. In triangleEFG, EF = 400, FG = 500, and GE = 600. Are these triangles similar, and if so, what is the scale factor?
A. similar, scale factor = 10
B. similar, scale factor = 100
C. similar, scale factor = 1000
D. not similar

Answer 1

Yes,\[
\frac{400}4=\frac{500}5=\frac{600}6=?
\]

Answer 2

\[
\frac{400}4=\frac{500}5=\frac{600}6=100

\]

Answer 3

B is your answer
