There are six types or classifications of triangles, and every triangle will fit into two classifications based on the angles of the triangle and the lengths of the triangle's sides.
A triangle can be an Acute Triangle, Obtuse Triangle, or Right Triangle based on its angles, and it can be an Isosceles Triangle, Equilateral Triangle, or Scalene Triangle based on its dimensions.
Please enter the angles of your triangle so we can determine what type it is.
