EUCLID, ALGEBRA, AND MENSURATION. Candidates in Scotland may answer two questions out of Section IV. if they omit Section IX. With this exception Candidates EUCLID. The square on PQ may be written "sq. on PQ," and the rectangle con. tained by PQ and RS, “rect. PQ, RS." SECTION I. Define a right angle, an oblong. Complete the following definitions : (a) Parallel straight lines are such as being produced ever so far both ways do not meet. (b) A square is a four-sided figure whose sides are all equal. (c) A diameter of a circle is a straight line drawn through the centre. Show that the following two statements are incor. rect: If unequals be added to unequals the wholes are unequal. All equal angles fill the same space. (These form one question.) SECTION II. 1. If two straight lines cut one another, the vertical or opposite angles will be equal. Two equal perpendiculars, PA, QB, are drawn to the line AB from points P, Q, on opposite sides of AB; AB is bisected in Ó. Show that POQ is a straight line. 2. The greater angle of every triangle is subtended by the greater side. BAC is a right-angled_triangle, right-angled at A; CD is drawn to any point D of the side AB. Show that CD is greater than CA, but less than CB. 3. The three interior angles of every triangle are together equal to two right angles. If two right-angled isosceles triangles have their bases equal, they will be equal in all respects. SECTION III. 1. Triangles upon equal bases and between the same parallels are equal to each other. If AB, one of the sides of the triangle ABC, be bi. sected in 0, and AC divided into three equal parts in E, D, show that the triangle EOD is one-sixth of the whole triangle ABC. 2. If the square described upon one of the sides of a triangle be equal to the squares described upon the other two sides of it, the angle contained by these two sides is a right angle. BAC is an isosceles triangle, AB being equal to AC, AD is drawn perpendicular to BC. Show that if the square on BC is less than four times the square on AD, the triangle BAC is an acute-angled triangle. 3. If a straight line be divided into two equal parts and also into two unequal parts, the rectangle contained by the unequal parts, together with the square on the line between the points of section, is equal to the square on half the line. Show that the square on the whole line is equal to four times the rectangle and smaller square above mentioned. SECTION IV. 1. In every triangle the square on the side subtending either of the acute angles is less than the squares on the sides containing that angle by twice the rectangle contained by either of these sides and the straight line intercepted between the acute angle and the perpendicular let fall upon it from the opposite angle. Show that the rectangle contained by the sides of a right-angled triangle can never be greater than half the square on the hypotenuse. 2. In any circle only two equal straight lines can be drawn from the same point, not being the centre, to the circumference, one on each side of the diameter drawn through the point. If in any diameter two points be taken equidistant from the centre, and four equal lines be drawn from these points to the circumference, the figure formed by joining the extremities of these four lines taken in order will be a rectangle. 3. If a straight line touch a circle and from the point of contact a straight line be drawn meeting the circle, the angles which this line makes with the line touching the circle shall be equal to the angles in the alternate segments of the circle. Two circles whose centres are A, B, touch externally in C; a common tangent meets the circles in P, Q. Show that the square on PQ is equal to four times the rectangle AC, CB. a ALGEBRA.
