...triangles, which are equal to them, are equal to one another. (2l6.) COR. 2. Hence, if two spherical **triangles have the three sides of the one equal to the three sides of the other,** or two sides and the included angle in the one, equal to two sides and the included angle, in the other,... | |

...the figure will be a parallelogram. Demonstration. Draw the diagonal BD ; the two triangles ABD, BDC, **have the three sides of the one equal to the three sides of the other, each to each,** they are therefore equal, and the angle ADB opposite to the side AB is equal to the angle DBC opposite... | |
