AN = 6 cm
RI = 8 cm
TA = 3.3 cm
NI = 1.6 cm

Use any or all of these facts to answer the following:
a) In two-column format prove that TAN  TRI.
b) Assume TAN is the image of TRI under a dilation. Is the dilation an expansion or a contraction? What is the scale factor?
c) Calculate AR. Show your work.
d) Use the Side-Splitting Theorem to find TN.
e) What is the ratio of the area of TRI to TAN?
