Part of a sequence of activities at http://mathhombre.blogspot.com/2009/10/geogebra-triangle-tuning.html
a. Collect at least 2 examples of each type of triangle. Where possible, try not to have the triangles be similar, where all the sides are multiples of another triangle.
b. Which were hardest to find? Was it something to do with the type or how you were looking?
