Question

1. name all similar relationships.

Explanation:

Step1: Calculate the ratios of the sides for each rectangle

For \(R_1\): \(\frac{10}{4} = 2.5\)
For \(R_2\): \(\frac{6}{2}=3\)
For \(R_3\): \(\frac{3.125}{1.25}=2.5\)
For \(R_4\): \(\frac{7.5}{3}=2.5\)

Answer:

\(R_1\sim R_3\) and \(R_1\sim R_4\) and \(R_3\sim R_4\)
