Geometry Important Formulas

Geometry Important Formulas

These formulas will come handy in the competitive exams like IBA, BIBM, Bank Jobs, EMBA, BCS. So save these formulas & memorize them.

Angles

Sum of Interior Angles of Polygon = (n-2)(180)

 

n = number of sides of a polygon

 

Central Angle = 2(Inscribed Angle)

 

Area

Square: A = a^2

Rectangle: A = lw

Parallelogram: A = bh

Trapezoid: A = .5(a+c)h, where a and c are the lengths of the parallel sides

 

Circles

π = pi = 3.1415

 

Area: A = πr^2

Circumference: C = 2πr

Central Angle = 2(Inscribed Angle)

Area of Sector = (x/360)πr^2

 

Perimeter

 

Square: P = 4l

Rectangle: P = 2w + 2l

Parallelogram: P = 2b + 2a, where a and b are the lengths of the non-parallel sides

Circle: P = 2πr

 

Triangles

 

Area: A = .5bh

Pythagorean Theorem: A^2 + B^2 = C^2 where A = one leg, B = the other leg, C = hypotenuse

 

Volume

Cube: V = a^3 where a is the length of a side

Rectangular Solid: V = hwl

Cylinder: V = πr^2h
