"Right-angled" Quotes from Famous Books
 ... 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, after the Revolution ...

... propositions of Euclid, but especially those which concern the equality of two figures, by cutting the one in pieces, and putting the pieces together again to make the other. In this manner, by cutting carefully in parts the squares on the two sides of the right-angled triangle, and arranging these parts carefully, one makes from them the square on the hypotenuse; that is demonstrating empirically the 47th proposition of the first book of Euclid. Now supposing that some of these pieces taken from ...

... around, he noticed that the southeast corner seemed to be more regular than the rest of the wall of the cave. In fact, it was almost a right-angled corner, and seemed to have been roughly cut into that shape. Instantly Burke was in the corner. He found the eastern wall quite smooth for a space about a foot wide and extending about two yards from the floor. In this he perceived lines of crevice marking ...

... this: What is the figure representing the acceleration of the motion of a piston, controlled by a crank which revolves with a uniform velocity? I stated it to be a right-angled triangle, and indicated, as I supposed, clearly enough, a simple method by which this could be shown. Your correspondent claims that the calculation, according to my own rule, gives a figure of a totally different form, and one that shows the acceleration, as well ...

... have shown the azimuth of Polaris to be a function of the latitude, and as the latitude is now known, we may proceed to find the required azimuth. For this purpose we have a right-angled spherical triangle, Z S P, Fig. 4, in which Z is the place of observation, P the north pole, and S is Polaris. In this triangle we have given the polar distance, P S 10 19' 13"; the angle at S 90; and the distance Z P, being the complement of the latitude as found above, or 90—L. ...
