346 TEE ELEMENTS OF PERSPECTIVE. COROLLARY IV. Removing from the preceding figure the unnecessary lines, and retaining only r' m and a v, as in Fig. 14., produce the line a r' to the other side of a, and make a x equal to a r'. Join x b9 and produce x b to cut the line of sight in n. M V N … X a R' Fig. 14. Then as x r' is parallel to m n, and a b! is equal to a x, v n must, by similar triangles, be equal to v m (equal to v t in Fig. 13.). Therefore, on whichever side of v we measure the distance v t, so as to obtain either the point m, or the point n, if we measure the sight-magnitude…
