"Right-angled triangle" Quotes from Famous Books
 ... Southern skirt of the Henry House plateau—in a line-of-battle which, with its left resting upon the Sudley road, three-quarters of a mile South of its intersection with the Warrenton Pike, is the irregular hypothenuse of a right-angled triangle, formed by itself and those two intersecting roads, to the South-East of such intersection. It is within this right-angled triangular space that the battle, now proceeding, bids fair to rage ...

... right-angled triangle, A B H express algebraically the value of the sine, co-sine, tangent, and co-tangent of angle A in terms of a, b, and h, they being the altitude, base, and ...

... characteristic of this type of mind to be interested in the tangibilities of geometry, hence it is not surprising to be told that Pythagoras "carried that science to perfection." The most famous discovery of Pythagoras in this field was that the square of the hypotenuse of a right-angled triangle is equal to the squares of the other sides of the triangle. We have already noted the fable that his enthusiasm over this discovery led him to sacrifice a hecatomb. Doubtless the story is apocryphal, but doubtless, also, it expresses the truth as to the fervid joy with ...

... recollection of ideas our faculty of reason depends, as it enables us to acquire an idea of the dissimilitude of any two ideas. Thus if you voluntarily produce the idea of a right-angled triangle, and then of a square; and after having excited these ideas repeatedly, you excite the idea of their difference, which is that of another right-angled triangle inverted over the former; you are said to reason upon this subject, or ...

... divinum of Presbytery that made the idea impossible to them. Yet why should it have been impossible in consistency even with that belief? It may be jure divino that the square on the hypothenuse of a right-angled triangle is equal to the sum of the squares on the sides, that he is a blockhead who believes otherwise, and that a permanent apparatus should be set up in every land for teaching this mathematical faith; and yet it may be equally ...

... hypotenuse; it comes from the verb ὑποτεινειν {hypoteinein} (c. ὑπο {hypo} and acc. or simple acc.), to stretch under, or, in its Latin form, to subtend, which term is used quite generally for 'to be opposite to'; in our phraseology the word hypotenuse is restricted to that side of a right-angled triangle which is opposite to the right angle, being short for the expression used in Eucl. i. 47, ἡ την ορθην γωνιαν ὑποτεινουσα πλευρα {hê tên orthên gônian hypoteinousa pleura}, 'the side subtending the right angle', which accounts for the feminine participial form ...

... in its bearings on the climate of western Europe, the whole subject of the climate of England is viewed from a new and interesting standpoint. In arithmetic, where the sum of the squares of the two sides of a right-angled triangle is illustrated by an example and later on in geometry the same proposition is taken up in a different way and proved as a universal theorem, new and interesting light is thrown upon an old problem of arithmetic. In United States history, ...

... form these into points for a star proceed as follows: Begin with the right-hand strip at the top and number all the strips from one to eight. Fold number one back toward the right, making at the fold a right-angled triangle. Fold the strip down again towards you, making another triangle which is folded back to the left on the first one. Slip the end of the strip under the square next to it and cut it off. Proceed in the same way with three, five, and seven. Then turn the form over and fold the strips two, ...

... knit, and tough as iron. His quiet but resolute look was not willingly cast downwards, his grey hair, brushed up in front, was as abundant as if he were still young. The straight lines of his nose formed a geometrically-drawn right-angled triangle. No moustache; his beard cut in Yankee fashion bedecked his chin, and the two upper points met at the opening of the lips and ran up to the temples in pepper-and-salt whiskers; teeth of snowy whiteness were symmetrically placed on the borders ...

... as well as his passengers and the whole of his crew. She has a heavy, rough spar for a mast, tapering towards the head and raking forward. The sail which they are now just hoisting is, in shape, like a right-angled triangle, with a parallelogram below its base; the hypothenuse or head of the sail is secured to a yard, like an enormous fishing-rod; the halyards are secured to it about a third of the way from the butt-end, and it is hoisted close up to the head of the mast. A tackle brings down the lower end ...
