There are several conservation laws in nature: conservation of mass, conservation of energy, of momentum, of angular momentum, of electric charge, and others.
Usually you would use some fact you know about the physical system, and then write an equation that states that the total angular momentum "before" = the total angular momentum "after" some event.
For example, various conservation laws (conservation of mass, of energy, of momentum, of angular momentum, of electric charge), Newton's Second Law, the Universal Law of Gravitation, etc.
angular momentum and angular velocity
angular mmtm is a cross product unlike linear momentum
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
Conservation of angular momentum.
it works on the basis of conservation of linear momentum
It is conservation of [angular] momentum.

Law of conservation of momentum applies to any body on which no external torque is acting.

More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.
This was because of laws of conservation of: momentum, angular momentum, and energy. In certain reactions, these were apparently not conserved; a hypothetical particle would resolve the observed discrepancy.This was because of laws of conservation of: momentum, angular momentum, and energy.

The conservation of angular momentum.
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
