1. regard triangle tri and the following facts:
segment ir || segment na
ta = 12 cm, ra = 3 cm, nt = 18 cm, an = 22

(a) what theorem or postulate proves triangle ant similar to rit?
(b) solve for ni by using the side-splitting theorem. show all work.
(c) what is the scale factor for similar triangles ant and rit?
(d) calculate ri. show your work.
(e) what is the ratio of the areas of the two triangles? show your work.
