1. Construct a triangle equal in area to a convex fivesided rectilineal figure ABCDE; AB is to be the base of the triangle, and AE the direction of one of its sides. 2. The area of any two parallelograms described on two sides of a triangle is equal to that of a parallelogram on the base whose side is equal and parallel to the line drawn from the vertex of the triangle to the intersection of the two sides of the former parallelograms produced to meet. 3. If from any point straight lines be drawn to the angles of a rectangle the sums of the squares on those drawn to opposite angles are equal. 4. The circle which passes through the middle points of the sides of a triangle passes also through the feet of the perpendiculars on the sides from the opposite angles, and also bisects any straight line drawn from the intersection of these perpendiculars to the circumference of the circumscribing circle. 5. If the vertical angle of a triangle be bisected by a straight line which also cuts the base, the rectangle contained by the sides of the triangle is equal to that contained by the segments of the base together with the square on the straight line which bisects the angle. Prove that this rectangle is also equal to that contained by two straight lines equally inclined to the bisector, one terminated by the base and the other by the circumscribing circle. 6. If four straight lines are proportionals, the rectangle contained by the extremes is equal to that contained by the means. If the exterior angle of a triangle be bisected by a straight line which cuts the base produced, the square on the bisecting line is equal to the difference of the rectangles of the segments of the base and of the sides of the triangle. 7. Define the cosine of an angle. Shew how to resolve the sum or the difference of two cosines into factors. If A + B + C = nπ, prove that cos 2 A + cos 2 B + cos 2 C + 1 8. Define the secant and the cosecant of an angle, and shew that they are the reciprocals of the cosine and the sine of the angle respectively. If sec B√3. sec A and cosec 2 B = cosec 2 A, find A and B in the most general form. 10. If 01 02 03 04 are so nearly equal that the cosine 0, of the difference of any two of them may be assumed to be unity, prove that the last equation in question 9 becomes 11. Shew how to solve a triangle, having given two sides and the included angle. If the third side only is wanted, shew how it may be obtained without first finding the other angles. If C 36° 52′ 12′′, a 70, b = 35, find A and B, having given log 3 = 0·4771213, and L cot (18° 26' 6") 10-4771213. 12. Find the radius of the inscribed and of any escribed circle of a triangle in terms of its sides. If A, be the area of the triangle whose base is the side a of another triangle and vertex the centre of the inscribed circle of the latter, and A', the area of another triangle having the same base and vertex the centre of the escribed circle which touches a, with similar notation for the other sides, prove that A1 A2 1 + A' A'2 A'3 ENGLISH.
