en two triangles ABC and DEF, such that: (1) AC =DF^ angle A is greater than angle Z), angle C is less than angle F; (2) AC = DF^ angle A = angle Z>, angle C is less than angle F; (3) AC = DF^ angle ^ = angle D, angle (7 = angle F. Apply triangleABC to triangle DEF and draw a diagram to… … Given A ABC and DEF, AC = DF, Z. A =/. D, and Z. C = Z. F.To prove A ABC = A DEF. Argument 1. Place A ABC upon A DEFso that A C shall fall uponits equal DF, A upon D)C upon F. 2 Then AB will become col-linear with BE, and Bwill fall somewhere onBEj or on its prolonga-tion. 3. Also CB will become…
