33.Draw obliques equidistant (that is, equally distant) from a perpendicular.
Draw first a horizontal, raise a perpendicular on its centre, and then draw a line from the top of the perpendicular to each end of the horizontal. The figure will then be an isoceles triangle, as in fig. 11.
34.Make a scalene triangle.(fig. 13.)
As it is not difficult to make a triangle of unequal sides, it will be well for the monitor to prescribe the length of one or more of them. Thus he may say: "Make a scalene triangle, of which the three sides shall measure one inch and two tenths; one inch; and eight tenths of an inch."
35.Make an equilateral triangle.(fig. 20.)
After the pupil makes the figures exactly, let the length of the sides he given, as one, two, three, &c. inches. Then require the point to be under the base, turned to the right, &c.
36.From a given point draw a perpendicular.
First draw a right line, then make the proposed point, and lastly draw the perpendicular.
27.Raise a perpendicular on the end of a right line.
38.Make a Rhomb or Lozenge.(fig. 21.)
