...From formulas (85) and (86), or those derived from them, it is easy to show, that B=A, when 6= a, or **that the angles at the base of an isosceles triangle are equal;** as, by taking a and b equal, the values of cos A and cos B would become equal. FORMULAS OF THE FOUR... | |

...immediately; and that three is the half of six. This immediate perception is immediate and intuitive judgment. **That the angles at the base of an isosceles triangle are equal, I** perceive by a process of reasoning, in which it will be acknowledged there is judgment. Another way... | |

...is a fact which all future geometrical analysis can only confirm and illustrate, and thus the truth **that " The angles at the base of an Isosceles triangle are equal** " becomes a fundamental part of celestial dynamics, and the Eureka of Archimedes an essential portion... | |

...without stating what it is fit for, — an absurdity as great, says the objector, as it would be to say **that ' the angles at the base of an isosceles triangle are equal** without adding to one another, or to any other angle.' Dr. Brown also, in arguing against this doctrine... | |

...propositions, are subsequently employed as major premises. Such, for example, are the propositions **that the angles at the base of an isosceles triangle are equal** ; that the three angles of every triangle are together equal to two right angles ; and that all equilateral... | |

...Though your brother's genius was all but catholic — I say all but ; for he could never demonstrate **that the angles at the base of an isosceles triangle are equal** — yet to me he generally showed the bright and sunny side of his nature ; and I need not tell you... | |

...shown that there is only one intelligible law, then that must be the actual law. Thus we may argue **that the angles at the base of an isosceles triangle are equal** (not because there is no reason why one should be greater than the other, but), because, if not, no... | |

...sum of the angles of a spherical triangle is greater than two right angles, and less than six. Show **that the angles at the base of an isosceles triangle are equal.** (9.) Express the cosine of an angle of a spherical triangle in terms of the cosines and sines of the... | |
