Examine $ΔABC$ and $ΔDEF$ at right.  

1. Assume the triangles above are not drawn to scale. Using the information provided in each diagram, write a mathematical statement describing the relationship between the two triangles. Justify your conclusion.

   Hint (a):

   Use the Triangle Angle Sum Theorem to find the unknown angle in each triangle.
   This will help you determine the relationship between the two triangles.

2. Find $AC$ and $DF$.

   Hint (b):

   The corresponding sides of similar triangles will all have equal ratios to one another.
