Answer: Its because instead of the sun being behind the earth therefor causing a shadow on the moon, it is away from the earth or behind the moon causing an eclipse.
Explanation: When the shadow of the earth is on the moon, it causes a shadow on the moon because the earth is a sphere. When the sun rotates away from the moon it prevents a shadow on the moon. Therefore causing a full moon and letting us see the entire side of the moon.
We see the entire side of the moon during a full moon because the sun will illuminate only half and we only see the entire face illuminated at the full moon.
Why do we only see one side of the moon?
Over the years, the Moon synchronized its rotation and translation movement with the Earth, that is: while completing a revolution around the Earth (translation), the Moon also completes a revolution around itself (rotation) . This makes it always have the same face towards our beautiful blue planet.
However, the Sun will always illuminate only half of the satellite, and we only see the entire face illuminated at the full moon. During the other phases, this illuminated face is at an angle that allows us to see only part of it. For the avoidance of doubt, during the waxing and waning quarters, we see half of the moon's illuminated face.
