Question

Are the triangles similar? if so, how would you prove it?

Answer 1

Not similar

Step-by-step explanation:

Two triangles are similar if their interior angles are the same or if their corresponding sides are proportional.

In this case, we know the lengths of their sides, so we need to prove that they are proportional.

Then, we can find the relation between the corresponding sides as:

`\begin{gathered} (25)/(108)=0.231 \\ (22)/(99)=0.222 \\ (21)/(90)=0.233 \end{gathered}`

Now, we can say that the triangles are not similar because all the ratios are distinct.

Therefore, the answer is Not similar.
