  TRIANGLES A triangle isa 3-sided polygon. Every triangle has three sides, three vertices and three angles. On the basis of sides of a triangle, triangles are of three types, An Equilateral Triangle, An Isosceles Triangle and A Scalene Triangle. All triangles are convex and bicentric. That portion of the plane enclosed by the triangle is called the triangle interior, while the remainder is the exterior. The study of triangles is sometimes known as triangle geometry and is a rich area of geometry filled with beautiful results and unexpected connections.

  On Basis ofLength of Sides, there are 3 types of Triangles • Equilateral Triangle • Isosceles Triangle • Scalene Triangle On Basis of Angles, there are 3 types of triangles • Acute Angled Triangle • Obtuse Angled Triangle • Right Angled Triangle
• 5.
  EQUILATERAL TRIANGLE Triangles havingall sides equal are called Equilateral Triangle. ISOSCELES TRIANGLE Triangles having 2 sides equal are called Isosceles Triangle.
• 6.
  SCALENE TRIANGLE Triangles havingno sides equal are called Scalene Triangle.
• 7.
  Triangles whose allangles are acute angle are called Acute Angled Triangle. ACUTE ANGLED TRIANGLE RIGHT ANGLED TRIANGLE OBTUSE ANGLED TRIANGLE Triangles whose 1 angle is obtuse angle are called Obtuse Angled Triangle. Triangles whose 1 angle is right angle are called Right Angled Triangle.
