Math Practice Topic: Triangle Types

Description: Determine whether a triangle is equilateral, isosceles, or scalene, and whether or not it is acute, right, or obtuse.

Adaptive Learning Progression: Triangles start out fully labeled, then later the angle measurements are removed, forcing you to use your best judgment.

Sample Levels (out of 6)

Determine whether the triangle is equilateral, isosceles, or scalene based on the length of the sides, and whether it is an acute, right, or obtuse triangle based on the angles.
