equal totwo sides ED, DF, of a triangle EDF,each to each, while the third side BG of the first is greater than the third side EF of the second,then the ande BAG of the first trianiile will be oreaterthan the angle EDF of the second. For, if not greater, the angle BA G must be equal toEDF or less… … TEOrOSITIOX X. THEOREM. If two triangles have the iJtree sides of the ove eqval to the.three sides of the other, each to each, the triartgles are equal. Let EDF and BAG be two triangles, having the sidoED=BA, the side EF=BG, and the side DF=AG\ thenwill the angle D=A, the angle E=B, and the angle…
