etwo triangles HAB, MDE there are two angles in one equal totwo angles in the other, each to each, and one side equal to oneside, opposite to one of the equal angles in each, viz. HA equal toDM; therefore the remaining sides are equal (26. 1.) each to each:wherefore AB is equal to DE. In the same… … the base BC is equal (4.1.) to the base EF, and the remaining an-gles to the remaining angles: the angle ABG is therefore equal tothe angle DEF: and the right angle ABK is equal to the right 196 THE ELEMENTS OF EUCLID.
