They turned a right-angled bend in the road, disclosing a straggling hamlet in a hollow below, and, farther away in the distance, a sweep of ocean. "Most any kind," said Mr. Higgins. "There's Needley now. All you've got to do is ask the first person you see about him." "Yes," said Madison, "but take yourself, for instance. Did this Patriarch ever do anything for you?" "He did," said Mr.
I would not willingly be rude, but the fact remains a posture in which she would not, I think, have sat for her photograph leaning back in a chintz-covered easy-chair, all the lines of direction about her parallel with the lines of the chair, her arms lying on its arms, and the fingers of each hand folded down over the end of each arm square, straight, right-angled, gazing into the fire, with something of the look of a sage, but one who has made no discovery.
Anaximander made geographical charts, which required considerable geometrical knowledge. Anaxagoras employed himself in prison in attempting to square the circle. Thales, as has been said, discovered the important theorem that in a right-angled triangle the squares on the sides containing the right angle are together equal to the square on the opposite side of it.
Among these we may mention one, viz., "The square of the hypothenuse of a right-angled triangle equals four times the area of the triangle, plus the square of the difference of the other two sides." This principle has been known to mathematicians by means of arithmetic and algebra, but has never before, we believe, been reduced to a geometrical demonstration.
Below the plug was a trigger, with a hook-shaped forward end, in such a position that when the plug was drawn back the hook would catch and hold the plug until the lower right-angled projection of the trigger was pulled back. This would release the plug, and the spring would then be driven forward and explode the cap.
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.
The Generalizations which respectively affirm that all the angles of a triangle are equal to two right angles, or that the square of the hypothenuse of a right-angled triangle is equal to the sum of the squares of the other two sides, rest upon an entirely different basis of proof from those upon which the Generalizations rest which respectively assert that water is composed of certain chemical constituents combined in certain proportions, or that the nerves are the instruments of sensation and of motion.
A. No; it must be either an isoceles or a scalene triangle. Square. Q. What is this? A. A square. Q. Why is it called a square? A. Because all its angles are right angles, and its sides are equal. Q. How many angles has it? A. Four angles. Q. What would it make if we draw a line from one angle to the opposite one? A. Two right-angled isoceles triangles.
I do not like the right-angled building of these towns, nor do I like the sound of Twentieth Street and Thirtieth Street; but I must acknowledge that the arrangement in Philadelphia has its convenience. In New York I found it by no means an easy thing to arrive at the desired locality. They boast in Philadelphia that they have half a million inhabitants.
Curly rosewood sofas and arm-chairs, and marbled and mirrored chiffonniers, and the like, were in such profusion upstairs as to do away with the air of bleakness common to a right-angled chamber of large size and middle-class arrangement. A fine grand piano stood open in a prominent place.
