...This, however, will become more manifest in diagrams. For instance, [let it be proposed to demonstrate] **that the angles at the base of an isosceles triangle are equal** *. Let the lines A, B, be drawn to the centre of a circle. If, therefore, he assumes that the angle... | |

...that any particular action isßt, and yet fit for no particular purpose, is just as absurd as to му **that the angles at the base of an isosceles triangle are equal** but neither to one another, nor to any other angles ; and we may with no less propriety talk, of the... | |

...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,... | |

...properties of triangles. We will begin therefore, if you please, at the Asses' Bridge. Do you think **that the angles at the base of an isosceles triangle are equal,** or not? A. I see no reason why they should be otherwise; for, being opposite to equal sides, both angles... | |
