The teache-.. presents a triangle to the class and asks the pupils to show its dimensions; the surface; and the perimeter. 3. By comparison, the teacher makes the pupils realize that a triangle is one-half the area of a parallelogram of the same dimensions. 4. The pupils are then led to discover and formulate the general principles ior finding the area ot a triangle. 5. The teacher takes several examples by illustrations to generalize the idea. TII.
