Question

Prove that the two circles shown below are similar.

Answer 1

I completely forgot how to do this so any help would be very much appreciated!

Answer 2

I don't know what your method is, but this is my way of doing it.

Since we know that if two figures are similar, they share a like pattern.

Look at the diameter of both the large and the small circles. Tell me those diameters.

Answer 3

The big circle is 12 and the small circle is 6

Answer 4

Do you notice a pattern there already? If not, then try out the diameter.

Answer 5

Sorry I meant the radius

Answer 6

The small circles diameter is half the size of the large circles diameter

Answer 7

Yes so that is how they are both similar.

Answer 8

Do you now get how?

Answer 9

Yes! Thank you

Answer 10

You're welcome :)
