Back

Triangles can be classified as Equilateral (all sides equal), Isosceles (two sides equal), or Scalene (no sides equal).

Front

What is a triangle classified by its angles?

Back

Triangles can be classified as Acute (all angles less than 90°), Right (one angle equal to 90°), or Obtuse (one angle greater than 90°).
