BE are equal since ^^ is a rectangle, and therectangle under EK and the sum of DE and ^i^7 is equal to twicethe triangle DEF; therefore the rectangle under a si<le of thesquare LN and the sum of BC and AP, the base and altitude ofthe triangle ABC, is equal to twice the triangle ABC. Def. A… … equal to BC, make the angle FEB equal to one of the angles ofthe rhombus, and draw AB parallel to BC to meet EB in B. JoinBF. In the triangle BEF inscribe the rhombus GK having an anglecoinciding with the angle BEF (64). Produce HG to meet ABand AC in L and M, and draw LR, MN parallel to GE.…
