Introduction
The parabola is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface. The focus and a corresponding on the plane, the locus of points in that plane that are equidistant from them is a parabola. The parabola can be applied in many areas, from automobile headlight reflectors to the design of missiles. It was studied by Menaechmus, a Greek mathematician. They are frequently used in physics and engineering.
How does the satellite dish works?
In satellite dishes, the dish on the receiving end has to be in a parabolic shape because if it isn’t, it can't transmit information; it can only receive it.
The receiving dish works in the exact opposite way of the transmitter. When a beam hits the curved dish, the parabola shape reflects the radio signal inward onto a particular point, just like a concave mirror focuses light onto a particular point.

Conclusion
We now understand:
· Satellite dishes are parabolic in shape
· There are three types of parabolic antennas
· The whereabouts of Parabola.
We also did not realize that:
· Parabola can be applied in our everyday lives;
· We can use it for communicating with each other
· The parabola theory can be applied in making things like headlight reflectors and missiles
· Parabola can be used in Physics and engineering.
