Suppose their is a triangle.
Now imagine we have 2 vectors that form 2 sides of that triangle, such that the head of one is joined to the tail of the other.
The 3rd side of the triangle will represent the resultant of the 2 vectors but in the opposite direction

Hey dear here your
answer ::
According to the triangle law,::
if two vectors acting on a particle at the same time are represented in magnitude and direction by the two sides of a triangle taken in one order,their resultant vector is represented in magnitude and direction by the third side of the triangle taken in opposite order.
Here two vectors are A and B and the resultant C is taken as the above rule
METHODS OF REDUCING FRICTION
There are a number of methods to reduce friction in which some are discussed here.
USE OF LUBRICANTS:
The parts of machines which are moving over one another must be properly lubricated by using oils and lubricants of suitable viscosity.
USE OF GREASE:
Proper greasing between the sliding parts of machine reduces the friction.
USE OF BALL BEARING:
In machines where possible, sliding friction can be replaced by rolling friction by using ball bearings.
DESIGN MODIFICATION:
Friction can be reduced by changing the design of fast moving objects. The front of vehicles and airplanes made oblong to minimize friction.
