If two triangles have two sides and the included angle of the one equal...and the included angle of the other, each to each, the triangles are equal in every respect. For, since two sides of given length intersecting at a given... | |

...CAG equal to the angle D (Post. 7) ; make AG equal to DE, and draw GC. Then the triangles AGC and DEF have two sides and the included angle of the one equal...and the included angle of the other, each to each ; consequently, GC is equal to EF (PV). Now, the point G may be without the triangle ABC, it may be... | |
