Question

why do the sun, the moon and the earth not lie in one and the same line in every full moon day?​

Answer 1

Answer:

because the Earth and Moon don't orbit in the same plane. The Earth is inclined in its orbit of the Sun, and the Moon is inclined in it's orbit of the Earth. ... Since this plane doesn't change, there's only two points in the orbit where it is exactly in line with either the Earth's equator or the Earth's orbit.
