...b + a + c = 2 R. Therefore, the sum of the angles of a triangle equals two right angles. Cor.—If **two triangles have two angles of the one equal to two angles of the other,** the third angles will be equal. If, now, a = d and b = e, For, (1) a + b + c = 2 R. and (2) d + e +... | |

...truth of the sixteenth, it would be a proof of both the sixteenth and seventeenth. It shows us that, **if two triangles have two angles of the one equal to two angles of the other, each to each** or together, their third angles are also equal. The corollaries to this proposition are not Euclid's.... | |

...these two angles are equal. But the angle A is common to the two triangles BAD and BAC. Hence, these **triangles have two angles of the one equal to two angles of the other,** and are consequently similar (Cor., Theo. IX). Therefore, Cor.—If from a point without a circle a... | |
