qual to the angle MDE.Therefore in the two triangles HAB, MDE there are two anglesin one equal to two angles in the other, each to each, andone side equal to one side, opposite to one of the equal anglesin each, viz. HA equal to DM; therefore the remaining sidesare equal *, each to each: wherefore… … BAG is equal to the angle EDF; wherefore the base BC isf 4.1. equal f to the base EF, and the remaining angles to the remain-ing angles: the angle ABG is therefore equal to the angleDliF: and the right angle ABK is equal to the right angleDEN, whence the remaining angle GBK is equal to the…
