This triangle can be used to investigate many characteristics of a triangle. Some examples below:
- Investigate relationships between side lengths and angle measures.
- Find relationships between the squares of the side lengths and the angle type of the triangle.
- Gather side-angle data for each of the
- Investigate congruency theorems. For example: Give students two side lengths and an angle measurement, how many triangles can be constructed?
- Try out Heron's Law.
- Investigate area.
