Side 14 - AB into two parts, so that the rectangle contained by the whole line and one of the parts, shall be equal to the square on the other part.
Side 15 - ... is termed a diameter. An arc of a circle is any part of the circumference. A sector of a circle is the space enclosed by two radii and the intercepted arc. When the radii are at right angles, the space is called a quadrant as to one-fourth of a circle. Half a circle is called a semicircle. A chord is a straight line joining the extremities of an arc, as a b.
Side 7 - AQ, at right angles to each other; in which place the sides AB, AC, of the given squares ; join BC ; then a square described on BC will be equal to the sum of the two squares described on AB and AC.
Side 14 - If in a circle two straight lines cut one another, the rectangle contained by the segments of the one is equal to the rectangle contained by the segments of the other.
Side 15 - A segment is any part of a circle bounded by an arc, and its chord, as E, F, G. 50. A semicircle is half the circle, or segment cut off by a diameter.
Side 7 - Art. 361, and divide the arc, ij, into the same number of equal parts as there are to be treads ; through the points of division, 1, 2, 3, &c., and from the wall-string to the front-string, draw lines tending to the centre, o ; then these lines will represent the face of each riser, and determine the form and width of the steps. Allow the necessary projection for the nosing beyond ae...
Side 15 - A Square is a four-sided figure, having all its sides equal, and all its angles right angles; as H.
Side 16 - Thus, to draw a line through a given point parallel to a given line...
Side 16 - The three interior angles of any triangle are together equal to two right angles.
Side 19 - P be the point at which a tangent is to be drawn. Draw the radius OP to the given point of tangency, and produce it any convenient distance beyond the circle. Erect a perpendicular to this line at P, as MT ; then is MT a tangent to the circle (172). FIG.
