Perspective and geometrical drawing adapted to the use of candidates for second and third-class teachers' certificates . = AD = AC = 4\ (Eig. 61.) Example 2.—Draw a cube, edges 4, right face at an angleof 60° and left face at an angle of 30° with H = 6, = 4^, scale Y = !• Cube to have an angle 4^ to left and2 within Draw , and 00 as before; find also , R ,L , R MP, L MP and MP (parallel perspective), as alreadyshown. Take A, i to left; join A ; erect AK = 4; joinK ; join also B ; through E draw EL parallel toAK; join E RMP and E LMP, and produce them backwardsto meet in Z and X. Mark off XC = 4; also ZD = 4;join D RMP and C LMP, also L R and ;through E draw EM, and through G draw GH, parallel toEL; join M L and H R to meet at N, completingthe required cube. Eor EM = EL = HG = AK = 4, and EG =EE = XC = ZD = 4; so also MN = HL = GE, etc. (Eig. 62.) Note.—The point E must always be determined by parallelperspective; hence necessity for finding MP; also DP coincide at 45°, and and MP coincide at 60°. 100 MISCELLANEOUS EXERCISES. 101 Exercise XY.—Figures in Angular Perspective,(In the following consider H = 6^ = i, scale ^ - V.) 1. A square whose sides are 4^, lies on ground; an angletouches 2 to right; angle 45°. 2. Draw same, 3^ to left arid 2 within ; right side makesangle of 60°. 3. Draw same, touching directly in front; angle .45°. 4. Draw a cube, of 4 edge, touching at a point 2 toright; angle 45°. 5. Draw same, 4 to left and V within ; angle 45°. 6. Draw a square pyramid, edge of base 4, height 8, angle45°; touches 4^ to left. 7. Draw same, 4 to right and 2^ within ; angle 45°. 8. Draw same, 2, to left and 2 within ; left and rightangles, 30° and 60° respectively. 9. Draw a triangular prism, each edge of base 3 and blong; standing on end, angle touching 4 to left; angles60° and 60°. 10. Draw a square p
