...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... | |
