...three pairs of coincident points. (3) To secure this the observer need only see that the condition that **the three angles of a triangle are together equal to two right angles** is satisfied by the scale indications. The " three point problem " may be solved by the scale with... | |

...inhabited, though a truth, is not a primary truth ; we believe it on secondary testimony. Nay, that **the three angles of a triangle are together equal to two right angles** is not seen to be true at once ; it needs other truths coming between to prove it. But that there is... | |

...be said, indeed, that tlie evidence altogether is not of equal cogency with the demonstration that **the three angles of a triangle are together equal to two right angles.** This may be freely granted, and if such a demonstration is required, the Sonnet-problem is no doubt... | |

...his statement of the pans a&inorum, and his demonstration, without drawing, of the proposition that **the three angles of a triangle are together equal to two right angles.** He shows no evidence of having hallucinations. Emotionally, he seems of an easy-going, optimistic temperament.... | |

...following simple- mathematical facts is of great assistance in modern machine gunnery. 1. Triangles. (a) **The three angles of a triangle are together equal to two right angles.** Thus, if any two angles are known, the remaining angle can be found. ABC + BCA + CAB = 2 right angles... | |

...prove it ? Does the perpendicular from the centre of a circle to a chord bisect the chord ? Obviously. **The three angles of a triangle are together equal to two right angles.** Are they ? Yes. Well, now, that's a funny thing. Why ? " If the above soliloquy fairly represents the... | |

...its several angles. Still, in a very great measure, the connection, as we said, lies naked before us. **The three angles of a triangle are together equal to two right angles.** If it is equilateral, it is equiangular, and vice versa. If a side is lengthened ceteris paribus, the... | |

...is hoped for. Perhaps there is nobody who would sacrifice his life for the sake of maintaining that **the three angles of a triangle are together equal to two right angles,** for such a truth does not demand the sacrifice of our life; but, on the other hand, there are many... | |

...so simple as this.. Suppose, for example, that in proving the theorem which says that the interior **angles of a triangle are together equal to two right angles, the** figure which we actually have on the paper in front of us is an isosceles right-angled triangle. What... | |
