Move points A, B and C around to make as many different types of triangles possible (acute, obtuse, right).
1. What do you notice about the circle and the vertices A, B and C?
2. What type of lines are the red dashed lines shown in the construction? How do you know?
3. What is point D called?
4. The radius of the blue circle will always be what length?
5. What is it called when a circle is drawn through the vertices of the triangle so that the circle goes around the triangle?
