Σελίδα 674 - The square of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two sides.
Σελίδα 664 - Proportion, when the ratio is the same between every two adjacent terms, viz. when the first is to the second, as the second to the third, as the third to the fourth, as the fourth to the fifth, and so on, all in the same common ratio.
Σελίδα 679 - MULTIPLY the radius, or half the diameter, by half the arc of the sector, for the area. Or, multiply the whole diameter by the whole arc of the sector, and take -f .of the product.
Σελίδα 679 - Find also the area of the triangle, formed by the chord of the segment and the two radii of the sector. Then...
Σελίδα 680 - Multiply the sum of the two parallel sides by the perpendicular distance between them, and half the product will be the area.
Σελίδα 681 - Sides 5 6 7 8 9 10 To find the area of a polygon: Multiply the sum of the sides (perimeter of the polygon) by the perpendicular dropped from its center to one of its sides, and half the product will be the area. This rule applies to all regular polygons. FIGURE 3.57 Polygons.
Σελίδα 688 - To 3 times the square of the radius of the segment's base, add the square of its height ; then multiply the sum by the height, and the product by -5236, for the content.
