For each triangle below, decide if it is similar to the triangle at right. If it is similar, justify your conclusion and complete the similarity statement $ΔABC ∼ Δ\text{___}$. If the triangle is not similar, explain how you know. Assume that the diagrams are not drawn to scale.  

1. 

   Hint (a):

   Find the measures of the unknown angles.
   Does this prove they are similar?

2. 

   Answer (b):

   $ΔABC~ΔMLK\left(\text{SSS}\sim\right)$

3. 

   Hint (c):

   Is there a zoom factor?
