A** **triangle is a plane figure with straight sides and three angles. All of the interior angles add up to 180 degrees. A triangle is a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices *A*, *B*, and *C* is denoted * ABC*.

**Formula**

**Area of triangle: **[ l×b /2 ]

**Perimeter of Triangle: **[ (a + b + c) ]

**Area of Equilateral Triangle:** [ (Sqrt (3)/4)×(side)² ]

**Area of Triangle SAS (2sides & opposite angle): **[ ½×a×b×SinC ]

**Where,**

l = length

b =breadth

a,b and c = sides of the triangle

A triangle is a three sided polygon consisting of three line segments linked end-to-end.

The interior angles of triangle always add up to 180 degrees

The exterior angles of triangle always add up to 360 degrees

**There are seven types of triangles:**

Isosceles triangle

Equilateral triangle

Scalene triangle

Right angle triangle

Obtuse triangle

Acute triangle

Equiangular

__Examples__:

**Calculate the area of a triangle with the given length as 3 and breadth as 4 cm.
Area = **[ l×b /2 ]= (3*4/2) = 12/2 =

**Calculate the Perimeter of triangle with the given sides as 3, 4 and 5 cm**

**Perimeter** = a+b+c = 3+4+5 = **12**

**Calculate the area of an equilateral triangle with the given side length as 4 cm
Area **=
