EUCLID, ALGEBRA, AND MENSURATION. Candidates in Scotland may answer two questions out of Section
IV. if they omit Section IX. With this exception Candidates
on ÞQ. may be written “sq. on PQ." and the rectangle con.
tained by PQ. and RS. "rect. PQ. RS.” SECTION I. Define a “straight line," a "rhombus." Write out the 12th axiom of Euclid.
Show that the following definitions are incomplete: * Of quadrilateral figures, a square bas all its sides equal." "An acute-angled triangle is that which has two acute angles.” * Parallel straight lines are such as do not meet however far they may be produced."
(These form one question.) SECTION II. 1. If the equal sides of an isosceles triangle be produced, the angles on the other side of the base shall be equal.
Show that this property can be proved by a method similar to that employed in the 4th Proposition.
2. If from the ends of the side of a triangle there be drawn two straight lines to a point within the triangle, these sball be less than the other two sides of the triangle, but shall contain a greater angle.
Write out the enunciations of any previous proposi. tions employed in this proof.
3. Straight lines, which are parallel to the same straight line, are parallel to each other.
If two adjacent sides of a parallelogram be parallel to two adjacent sides of another parallelogram, the other sides will also be parallel.
SECTION III. 1. Triangles upon the same base and between the same parallels are equal.
Construct a triangle equal to a given triangle and having a base three times as great.
2. To a given straight line to apply a parallelogram which shall be equal to a given triangle, and have one of its angles equal to a giren rectilineal angle.
To one of the sides of an equilateral triangle apply an equal parallelogram having one of its angles equal to that of the given triangle.
3. If a straight line be divided into any two parts, the square on the whole line is equal to the squares on the two parts, together with twice the rectangle contained by those parts.
[It may be assumed that parallelograms about the diameter of a square, are likewise squares.]
Show algebraically that the squares on the two parts are always greater than twice their rectangle except when the line is bisected.
SECTION IV. 1. In obtuse-angled triangles, if a perpendicular be drawn from either of the acute angles to the opposite sido produced, the square on the side subtending the obtuse angle is greater than the squares on the sides containing the obtuse angle, by twice the rectangle contained by the side upon wbich, when produced, the perpendicular falls and the straight line intercepted without the triangle between the perpendicular and the obtuse anglo.
If the triangle be isosceles, the square on the side subtending the obtuse angle is equal to twice the rectangle contained by either side and the straight line made up of that side and the straight line intercepted as in the proposition.
2. Equal straight lines in a circle are equally distant from the centre.
AB, AC are two equal chords of a circle at right angles to each other. Show that they are sides of a square inscribed in the circle.
3. If a straight line touch a circle, and from the point of contact a straight line be drawn cutting the circle, the angle which this line makes with the line touching the circle shall be equal to the angles in the alternate sogments of the circle.
If a targent be defined as the limiting position of a secant, show that the tangent to a circle is perpendicular to the radius drawn to the point of contact.
