Side 12 - AB be the given straight line ; it is required to divide it into two parts, so that the rectangle contained by the whole, and one of the parts, shall be equal to the square of the other part.
Side 10 - The logarithm of a quotient is equal to the logarithm of the dividend minus the logarithm of the divisor.
Side 14 - In equal circles, angles, whether at the centres or circumferences, have the same ratio which the circumferences on which they stand have to one another ; so also have the sectors.
Side 13 - To draw a straight line from a given point, either without or in the circumference, which shall touch a given circle.
Side 15 - In the ordinary or sexagesimal system, a right-angle, which is used as the measure of all plane angles, is divided into 90 equal parts, called degrees; a degree is divided into 60 equal parts, called minutes ; and a minute into 60 equal parts, called seconds.
Side 18 - Ans. ty. 7. Prove that the sides of any plane triangle are proportional to the sines of the angles opposite to these sides. If 2s = the sum of the three sides (a, b, c) of a triangle, and if A be the angle opposite to the side a, prove that sin A = ^ Vs (s -a)(s — b) (s — c).
