They are at 'right-angles', with the Earth at the corner of the right angle.

There are two phases of half moon, known as first quarter and third quarter. At first quarter, the Moon is one quarter of its journey around Earth, measured from new moon. If you look straight at a first quarter half moon, the Sun should be about 90° to your right, and you would see it in the evening. At third quarter, the Moon is three quarters of its journey around Earth, measured from new moon. If you look straight at a third quarter half moon, the Sun should be about 90° to your left , and you would see it in the early hours of the morning. We don't see that as often, as we are more likely to be in bed. If you look carefully and the conditions are right, you will see half moons during daylight.
during the first and last quarter of the moons gravitational
First quarter and third quarter phases of the moon produce the least variation in the tides.
First Quarter occurs when the moon is at right angles with respect to the Earth and sun. During this phase, the moon has completed one quarter of it's orbit around the Earth and an observer on Earth will see half of the moon illuminated.

During the entire two weeks from First Quarter to Third Quarter, more of the moon's lighted surface faces toward Earth than faces away from it.
Yes.
first quarter and last quarter
Exactly 50% of the moon is illuminated by the sun at every instant of time (except during a lunar eclipse).From our vantage point on earth, the amount of the illuminated half that we can see at any time changesduring the month."First Quarter" means the first quarter of the moon's entire cycle of phases ... about 7.4 days after the"New Moon". At that time, we see half of the illuminated part of the moon ... you'd call it a "half moon".

first quarter and third quarter phase.
The sun reflects on the moon differently when the moon moves around the earth therefore, creating the change to a first quarter moon.
The Moon is in the middle at New Moon, but the Earth is in the middle at Full Moon. At first and last quarter the Moon is at the right-angle in a right-angled triangle.
Sun-Moon-Earth form a right triangle in this case.
