E=MC2. Energy = Mass [multiplied by the speed of light squared].
So, yes, they are.

Energy can travel through space (a vacuum) at the speed of light in tiny mass-less packets called photons. When the energetic photons strike matter having mass because of its protons, neutrons and electrons it interacts with the electrons kicking them up into higher more energetic orbits or out of the atom entirely if ionized. When the electrons return to rest states (lowest possible orbits) in one or more steps, one or more new photons are released carrying away the excess energy. At no time has a photon become an electron or vice versa.
Energy can be organized and stored as in a pendulum which has maximum height (potential energy) or maximum speed (kinetic energy) or a combination of the two at positions between the top and bottom of the swing. The pendulum "has" energy when operating but its mass (matter) never becomes energy.
During nuclear fission or fusion a tiny amount of the "glue" that holds matter together is converted into energy per Einstein's equation E = Mc2 accompanied by a slight change in mass (mass discrepancy). But the glue is either mass or energy, not both.

No. Below are the differences of matter and energy
Matter occupies space while energy does not.
Some matter can be seen but only the effects of energy can be seen.
Energy can interact with matter, causing the matter to change shape, change state, move, stop, go faster, slow down, gain heat or lose heat

Not the same. Matter is made out of fermions, Energy has several forms (kinetic, potential, etc), only some of which are made out of particles (bosons). However, there are reactions whereby matter and energy can be interconverted.

There are arguments both ways on this. You can convert one to the other but they are different states of being. A candle wick is one thing. Light it and it is changed into light, heat, and ash. The sum total of all elements in the process is unchanged. This is what is meant by "The amount of matter before and after the reaction in question remains the same".
See also "Law of conservation of mass" and "Law of conservation of matter."

It is not possible to say that matter and energy are same.They are interconvertable.May be we can say that matter is the compressed form of energy...

they are not the same.the truth is that matter is made up of energy(string theory)

E=mc^2
They can be interconverted under some circumstances.
