Question

Prove that the two circles shown below are similar.​

Answer 1

Because we can transform circle A into circle B by using transformations, we conclude that circle A and B are similar.

How to prove that the two circles are similar?

We know that two figures are similar if one is a transformation of the other. So let's find the transformations that we need to apply to circle A to get circle B.

First, let's move the center. We can see that we need to translate circle A 5 units down and 3 units to the left.

Now, the radius of circle A is 5 units, while the radius of circle B is 2 units, then we have a scale factor k such that:

k*5 units = 2 units

k = 2/5

Then, if we apply the transformations to circle A.

• shift of 5 units down.
• shift of 3 units left.
• dilation of scale factor 2/5.

We get circle B, so circle A and circle B are similar.
