"Acute angle" Quotes from Famous Books
 ... precisely at right angles with the line of light passing from the sun to the moon. At this moment, then, the imaginary lines joining the sun, the moon, and the earth, make a right angle triangle. But the properties of the right-angle triangle had long been studied and were well under stood. One acute angle of such a triangle determines the figure of the triangle itself. We have already seen that Thales, the very earliest of the Greek philosophers, measured the distance of a ship at sea by the application of this principle. ...

... one opening a 25 c c. pipette nearly filled with sulphuric acid, sp. gr. 1.4, the lower point of which just dips below the mixture in the flask, and the upper end, carrying a rubber tube and pinch cock to control the flow of acid. Through the other opening passes a glass tube bent at an acute angle and connected by a short rubber tube to an adjoining flask, two-thirds filled with decinormal baryta solutions. These connections are all made air tight. Sulphuric acid is allowed in small portions at a time to flow into the mixture. Carbonic acid is evolved, and, passing ...

... thousand feet above. On the opposite side a square-faced buttress crowded the trail to the very brink of the canon. The trail followed along the foot of this buttress for a hundred feet or more, and at the edge it again turned from the gorge at an acute angle. At the turning-point a cleft, twenty feet wide, cut the cliff from the river-bed to a point far above the trail. A bridge had spanned the cleft, but it was gone. The accident had been caused by the giving way of the bridge when the stage was ...

... yellow tint, and get a few white spots, and the old buck assumes a dark slaty colour; the horns resemble those of a young spotted deer, with both the basal and upper tines very small, the former pointing directly upwards at a very acute angle, and the latter directed backwards and inwards, nearly at a right angle, occasionally pointing downwards" (Jerdon). McMaster says: "I can corroborate Jerdon's statement that the young of this deer are beautifully spotted; but, although I have seen many specimens, ...

... degrees. From this same tube, two small branches, about a foot apart, were sent off; one pointed downwards, and the other upwards. This latter case is remarkable, as the electric fluid must have turned back at the acute angle of 26 degs., to the line of its main course. Besides the four tubes which I found vertical, and traced beneath the surface, there were several other groups of fragments, the original sites of which without ...

... is reduced by first extending the elbow to free the lower fragment from the triceps, and then, while making traction through the forearm, manipulating the fragments into position, and finally flexing the elbow to an acute angle and supinating the forearm. In this way the triceps is put upon the stretch and forms a natural posterior splint. A layer of wadding is placed in the bend of the elbow to separate the apposed skin surfaces, the arm placed in a ...

... rock, to find a point upon which he would be able to make some impression with his implements; but the fragment, which had probably remained there since the deluge, without having been honoured by a visit from a naturalist, was worn quite smooth by time, and presented no acute angle, within reach, upon which his hammer could make any impression; nor could he climb it for it rose from its base in almost a perpendicular line. The more he scrutinised, the more anxious was he to obtain specimens, and he determined to blast the rock. ...
