...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...

...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 great...

...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...
