Triangle Puzzle Introduction. The following activities can be
... You may like to consider the area of each triangle and note that when all the triangles are used the different shapes all have the same area (as long as there are no overlapping triangles). You could investigate the smallest and largest perimeters. In doing this you may need to measure or calculate ...
