 Two triangles are equal if two sides and the included angle of the one are equal respectively to two sides and the included angle of the other (sas = sas). Hyp. In A ABC and A'B'C', AB = A'B', BC = B'C', and Z B = Z B'.  The Elements of Solid Geometry - Page 94by William C. Bartol - 1893 - 95 pagesFull view - About this book
