So it can keep it's direction
The most streamline shape is the teardrop-shape or the better known as the aerofoil.That is the reason why the airplane body and wings is shaped like a teardrop.This shape reduces air pressure on the object thereby increasing air flow in return increasing the speed of the body.
To have less air resistance (in the case of rockets, while they are still in the atmosphere).
It is a three sided straight lined shape with 3 interior angles that add up to 180 degrees.

144 are in a standard pack. Also referred to as a "gross" of bottle rockets

they have a stream-lined shape
One example is that the dolphin has a stream-lined body.
stream lined body of a fish helps to reduced friction
its smooth
a bird's shape is stream lined + you have bad grammar in your question+ it shows how a birds body is suited to flying

having a stream lined body make you able to move swiftly and efficiantly through air or water because it lessens the area effected by air or water risistance
It makes it easier for them to travel through the water.
A fairing makes the bike more stream lined, reduces wind resistance.
Because they wanted to copy the shape of jets and rockets
