Candidates who present themselves for the whole examination may omit questions 2, 3, and 5. Candidates who present themselves for the partial examination will confine themselves to the questions in Plane Geometry. NOTE 2. State what text-book you have studied, and to what extent. I. PLANE GEOMETRY. 1. (a) Define the symmetry of a figure with respect to an axis and with respect to a point. (b) Prove that if a figure is symmetrical with respect to two axes perpendicular to each other, it is also symmetrical with respect to the intersection of these axes. 2. An angle formed by a tangent and a chord is measured by one-half the intercepted arc. 3. To bisect a given arc or angle. 4. (a) If a perpendicular be drawn from the vertex of the right angle to the hypothenuse of a right triangle, the two triangles thus formed are similar to each other and to the whole triangle. (b) What can you say of the perpendicular as compared with the segments of the hypothenuse? Why? (c) What of either side about the right angle? Why? 5. On a given straight line to construct a polygon similar to a given polygon? 6. The circumferences of two circles are to each other as their radii, and their areas are to each other as the squares of their radii. II. - SOLID AND SPHERICAL GEOMETRY. 7. If a straight line and a plane are parallel, the intersection of the plane with planes passed through the line are parallel to that line and to each other. 8. Define a prism. Two prisms are equal, if three faces including a triedral angle of the one are respectively equal to three faces similarly placed including a triedral angle of the other. 9. Every section of a sphere made by a plane is a circle. 10. Between what two limits does the sum of the angles of a spherical triangle lie? Write expressions for the surface and volume of the cylinder, cone, and sphere. September, 1880. [State what text-book you have studied and to what extent.] 1. To draw a common tangent to two given circles. 2. The bisector of an angle of a triangle divides the opposite side into segments which are proportional to the adjacent sides. 3. The area of a parallelogram is equal to the product of its base and altitude. 4. How do you find the area of a trapezoid? The areas of similar polygons are to each other in what ratio? Of all plane figures having the same area what one has the least perimeter? 5. If a straight line is perpendicular to each of tv straight lines at their point of intersection, it is perpendicula. to the plane of those lines. 6. A triangular pyramid is one-third of a triangular prism of the same base and altitude. 7. Define the terms, spherical excess and tri-rectangular triangle. The area of a spherical triangle is equal to its spherical excess (the right angle being the unit of angles, and the tri-rectangular triangle the unit of areas). June, 1881. NOTE 1.
