The triangles are similar. State the reason and complete the similarity statement.

• $\Delta JKL\sim\Delta ABC$ by $SSS\sim$

• $\Delta JKL\sim\Delta BCA$ by $SSS\sim$

• $\Delta JKL\sim\Delta CAB$ by $SSS\sim$

• $\Delta JKL\sim\Delta BCA$ by $SSS\sim$

Answer explanation

The order of the points matter! The endpoints of the shortest sides have to line up! Same with the longest sides!

Using (SSS, AA, SAS) can you determine must be similar? If so, explain why.

• Yes, by SSS

• Yes, by AA

• Yes, by SAS

• There is not enough information to prove similarity
