- 4. TRIANGLES Triangle is 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 plane enclosed by the triangle is called interior of the triangle , while the remainder is exterior. The study of the triangles is sometimes known as triangles geometry and is a rich area of geometry filled with beautiful results and unexpected connections.
- 5. Types of triangles On the basis of length of sides, there are three types of triangles Equilateral triangle Isosceles triangle Scalene triangle On basis of angles,there are three types of triangles • Acute angled triangle • Obtuse angled triangle • Right angled triangle
- 6. Equilateral Triangle A triangle having all sides equal called equilateral triangle
- 7. Isosceles Triangle Triangles having 2 sides equal are called isosceles triangles.
- 8. Scalene Triangle Triangles having no side equal are called scalene triangles.
- 9. Acute Angled Triangle Triangles whose all angles are acute are called Acute angled triangles. Obutse Angled Triangle Triangles whose one angle is obtuse is called Obtuse angled triangles. Right Angled Triangle Triangles whose one angle is right angle are called Right angled triangles.
