Polygons

Perimeter of a regular polygon P = n X c (n is the number of sides, c is the side

length)

Area of a regular polygon A = p X a / 2 (p is the perimeter, a is the apothem)

Interior angle Sum of interior angles = (number of sides – 2) X 180

degrees Interior angle = sum of interior angles / # of sides

Exterior angle Exterior angle = sum of exterior angles / # of sides

Apothem Apothem = 2 X area / perimeter

Trapezoidal Prism

Surface Area of a Trapezoidal Prism = a(l + h) + b(l + h) + lc + ld.Where,a, b, c, d are sides of the trapezium.h = Altitude and l = Height of the prism.

Probability

Basic counting rule 2 steps

A x B 3 steps

A x B x C

Probability of an outcome P(a) = # of favourable cases / # of possible cases

Probability of an event in an equally probable space P(a) = # of favourable outcome to occur / # possible
