1. for triangle tri, the following facts are given:
segment an || segment ri
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 triangle tan ~ triangle tri.
b) assume triangle tan is the image of triangle 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 triangle tri to triangle tan?
