How do I answer this question :)))

Answer 1

The first triangle.

Explanation:

The sides LM, MN, and LN of Δ LMN have sides of lengths 15√2, 15 and 15 respectively.

Now, in the first graph, the sides of the graphed triangle are 3√2, 3 and 3 respectively.

So, the ratio of the corresponding sides is
`(15√(2) )/(3√(2) ) = (15)/(3) = (15)/(3) = 5`

Therefore, the first graphed triangle is similar to Δ LMN using the SSS similarity theorem. (Answer)
