Triangles can be classified based on their sides and angles. Based on sides, triangles can be equilateral (all sides are equal), isosceles (two sides are equal), or scalene (no sides are equal). Based on angles, triangles can be acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is exactly 90 degrees).
By definition, all triangles have 3 sides.
