**SSC TRICKS - TRIANGLE FORMULAS**

### Here are some very important formulas for triangles.

A. area of any triangle:

a. Area of a triangle =1/2 x Base x Height.

b. Area of a triangle = root(s(s-a)(s-b)(s-c))

where s = (a + b + c)/2

and a, b, c are the sides of the triangle.

2. Equilateral triangle area= [root (3)/4]*side^2

Equilateral triangles height (h) = (root3 /2) *a

3. Area of an Isosceles triangle = (b/4) * root (4a^2 - b^2)

Where a= one of two equal sides of isosceles triangle.

And b= third side of isosceles triangle (not equal to two sides).

**B. INCIRCLE AND CIRCUM CIRCLES: Formulas for calculating Incircles and circum circles of Triangles**

1. Radius of incircle of an equilateral triangle = a /(2root3)

Where a=side

2. Radius of circumcircle of an equilateral triangle = a/root3

3. Radius of incircle of a Scalene triangle of area P and semi-perimeter s = P/s

And Radius of Circum-circle of Scalene triangle = (a*b*c)/(4*area)

Where a, b, c are sides of scalene triangle.

C. In a right angled triangle: Pythagoras theorem

Hypotenuse)^2 = (Perpendicular)^2 + (Base)^2

**D. PERIMETER : Triangle formulas for calculating perimeter**

1. Scalene triangle perimeter = a+b+c

Where a,b,c are the sides of triangle.

2. Isoceles triangle perimeter = 2a+b

Where a=one of two equal sides

And b= 3

^{rd}unequal side
3. equilateral = 3a
