Tutogali49. two triangles aabc and aa'b'c' are said to beperspective from a point p if the lines formed bycorresponding points (the lines aa', bb', andcc') are concurrent at p. two triangles are saidto be perspective from a line m if the intersectionpoints of corresponding sides (the pointsab n a'b', bc n b'c', and ca n c'a') arecollinear on m. (see figure 3.9)part of desargue's theorem: if two trianglesare perspective from a point, then they areperspective from a line. a. create a diagram of desargue's theorem inwhich the point of perspectivity is betweenthe two triangles. b. create another diagram in which the pointof perspectivity is interior to both triangles. the part of
