Question

Are the triangles similar? If they are, identify the similarity ratio.

Answer 1

Answer: A

Explanation:

If you multiply all the sides of the first triangle it result in the second triangle,

Answer 2

Option 1. Yes, the similarity ratio is 1:3.

Explanation:

If the given triangles are similar then the ratio of all their sides are same.

So to prove the triangles as similar we will follow the statement reverse. Means to prove the triangles similar we will show the ratio of sides as same.

`(3)/(9)=(5)/(15)=(6)/(18)`

`(1)/(3)=(1)/(3)=(1)/(3)`

Which clearly tells us that all sides are in the same ratio of 1:3 that means both the triangles are similar.
