Maths – Parallel lines and properties relating to parallel lines

Properties of Parallel Lines –

  • The basic characteristic of Parallel Lines is they never meet at any point
  • The distance between two Parallel Lines would always be same at every point
  • Any third line will cut Parallel Lines at same angles
  • Any straight line cutting Parallel Lines is called Transversal
  • Two Transversals cutting Parallel lines at same angle would also be Parallel in themselves
  • Any line Parallel to one Parallel Line would be Parallel to all Parallel Lines

CTET and State TET Maths – LCM and HCF Concepts

LCM stands for Lowest Common Multiple, and HCF stands for Highest Common Factor.

The key to telling the difference between these two things is knowing the difference between a multiple and a factor.

A multiple of an integer (whole number) is any integer that appears in its times table. For example, the multiples of 3 are 3, 6, 9, 12, and so on.

A factor of an integer is any integer that divides the integer with no remainder. For example, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

We use LCM and HCF to compare two (or more) integers. Read More
