Use the applet below to explore the properties of equilateral and isosceles triangles. What do you notice about the relationships between the side lengths and angle measurements of equilateral and isosceles triangles?
1. What do you notice about the side lengths of equilateral triangles?
2. What do you notice about the angle measurements of equilateral triangles? Do you think this is true for all equilateral triangles?
3. If a triangle has two 60 degree angles, what do you think must be true about the side lengths of that triangle?
4. What do you notice about the side lengths of isosceles triangles?
5. What do you notice about the angle measurements of isosceles triangles? Do you think this is true for all isosceles triangles?
