During a quarter moon, the Sun, Earth, and Moon are positioned at a right angle to each other. This alignment occurs when the Moon is either in its first quarter or last quarter phase, with the Earth located between the Sun and the Moon in the case of the first quarter, and the Moon positioned between the Earth and the Sun during the last quarter. As a result, half of the Moon's surface facing Earth is illuminated, creating the distinct half-moon appearance.

When the Sun, Earth and Moon are lined up in such a way that the full moon moves into the Earth's shadow, it creates a lunar eclipse.
During a first quarter moon, the Earth is positioned between the Sun and the Moon. The Moon is at a 90-degree angle relative to the Earth and the Sun, meaning that half of the Moon's surface is illuminated by sunlight, which appears as a half-moon from Earth. This phase occurs roughly a week after the new moon and is part of the lunar cycle.
During a lunar eclipse, the moon is in Earth's shadow. So it must be 'behind' the Earth, with the sun in front. To put it another way, they're lined up like this: Sun ................................................................................................................ Earth .. Moon
Sun-Moon-Earth form a right triangle in this case.
During a quarter phase of the Moon, either the first or third quarter, the Earth, Moon, and Sun are positioned at approximately right angles to each other. In the first quarter phase, the Moon is located between the Earth and the Sun, while in the third quarter phase, the Earth is between the Moon and the Sun. This positioning causes half of the Moon's surface to be illuminated and visible from Earth, creating the characteristic half-moon appearance.

-- During a lunar eclipse, the moon is in Earth's shadow. -- During a solar eclipse, a small part of Earth is in the moon's shadow. -- In order for either of these to happen, the Sun, Moon, and Earth must be all lined up. -- New Moon and Full Moon are the phases when Sun, Moon, and Earth are all lined up.
During the New moon, the lighted side of the Moon is the OTHER side, the side we never see.
During a solar eclipse, the moon is lined up directly in between the Sun and the Earth, blocking out the sun's light.
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.
They are at 'right-angles', with the Earth at the corner of the right angle.

A quarter moon, also known as a first or last quarter moon, appears as a half-circle or semicircle when viewed from Earth. During the first quarter, the right half is illuminated, while in the last quarter, the left half is lit. This shape results from the relative positions of the Earth, Moon, and Sun.
