Problem 1. 2(4;--3) = 79+3X (corresponding angles of /lines). Then 8x--6 = 79+3; X=ij. Check: 79+3a;=79 + 51 = 130, 8x--6=136--6 = 130. The adjacent angle = 500. Problem 2. 3--5 = 5(x--7) (alternate interior Z s of // lines). Lesson 5: page 145 through Problem 13, page 146 1n. Problems on Constructions Show on board how to do Problem 1. Then have class practice at their desks with compasses and straight-edge till they can draw at a given point on a straight line (drawn in any direction on the paper) a perpendicular to the line. Assign Problems 2 to 7 for home work. Direct the pupils to make the construction lines plain and not to erase them. Teacher show how to do Problem 8 and make clear that either point G or point F may be used, but only one is needed. Problem 9. A B must be prolonged. Give Problems 10 to 13 as home work. In Problem 10 explain that the word altitude used here means the altitude line drawn from the vertex of the angle. Lesson 6: to Problem 24, page 148 Teacher show class how to do Problem 15. Have class practice at their desks bisecting given lines drawn in any direction on the paper. Assign Problems 16, 17, and 18 (or two of them) for home work. Teacher show Problem 19 and have class practice. Assign Problems 20 to 23 for home work. Problem 20. The bisectors should meet at a common point. Problem 21. The sum of the halves of the two parts of a straight angle equals a right angle. Problem 22. The halves of equals are equal, i.e., b = a, but if corresponding angles are equal the lines are parallel. Problem 23. a and b are halves of supplementary angles or of 1800, or 900, as the sum of x, ...
