N, and touch AB, CD at M and N, becausethe zls at M and N are rt. zls. Hence PEG, bisecting one of the L s between AB andCD, is a locus of centres of circles touching AB and CD. Similarly HEK, bisecting the other L between AB andCD, is a locus of centres of circles touching AB and CD. Note. A… … Let ABC be the given triangle.It is required to inscribe a circle in ABC.Bisect the Is ABC, ACB by the st. lines BD, CD,intersecting at D.. Then BD is a locus of centres of circles touching thesides BA, BC. (IV., 17.) And CD is a locus of centres of (urcles touching thesides^CA, CB. Hence D is the…
