; I. 34. .-. A ABC =^ DBC. Ax. 7. Q. E. D. Ex. 1. If P be a point in a side AB of a parallelooramABCD, and PC, PD be joined, the triangles PJ^D, PBC oietogether equal to the triangle PDC. Ex. 2. If A, B be points in one, and C, D points inanother of two parallel straight lines, and the lines AD,… … Let AS ABC, DBF be on equal bases, BC, EF, andbetween the same Us BF, AD. Then must A ABC= A DBF. From B draw BG 11 to CA to meet DA produced in 0. From F draw FH \\ to ED to meet AD produced in E. Then CG and BH are parallelograms, and they are equal, *.• they are on equal bases BC, BF, and…
