Classifying Triangles By Sides By Angles

Triangles Classified by Sides Scalene triangle: A scalene triangle is a triangle that has no equal sides. The following is a scalene triangle.

Triangles Classified by Sides Isosceles triangle: An isosceles triangle is a triangle that has two equal sides. The following is an isosceles triangle.

Triangles Classified by Sides Equilateral triangle: An equilateral triangle is a triangle that has three equal sides. The following is an equilateral triangle.

Triangles Classified by Angles Right triangle: A right triangle has a 90 degrees angle.The following is a right triangle.

Triangles Classified by Angles Obtuse triangle: An obtuse triangle has one angle that is bigger than 90 degrees (Obtuse angle). The following is an obtuse triangle.

Triangles Classified by Angles Acute triangle: In an acute triangle, all angle are less than 90 degrees, so all angles are acute angles.The following is an acute triangle.
