As you drag point B, notice the angles of the triangle. Acute triangles have angles with measures that are... Select all that apply:
You just looked at this triangle, but we can learn about obtuse triangles from it. Angle B is the key. What do you need to remember about obtuse triangles?
Observe what stays the same no matter what changes you make. What did you notice? Why do you think it's important?
Drag the blue point on the triangle until you have two sides that have the same length. This triangle has a special name: isosceles right triangle. What would be the measures of the other two angles for all isosceles right triangles?
As you have probably already determined, an equiangular triangle is also an equilateral triangle. All equiangular triangles have all angles that measure ___________ degrees.
