General form of Prime Numbers

Every prime number can be expressed in the form of 6n+1 or 6n-1 except 2 and 3.
But every number which can be represented in the form of 6n+1 or 6n-1 is not prime. 
Example: 35 can be expressed as 6n-1 where n is 6 but its not a prime number.

Ceva’s Theorem 

Ceva’s theorem is a theorem about triangles in Euclidean plane geometry. Given a triangle ABC, let the lines AO, BO and CO be drawn from the vertices to a common point O (not on one of the sides of ABC), to meet opposite sides at D, E and F respectively. (The segments AD, BE, and CF are known as cevians.)

Alternate segmemt theorem 

Alternate segment theorem. The angle between the tangent and chord at the point of contact is equal to the angle in the alternate segment.
