How are the sun moon and earth lined up during a quarter moon?

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.

During the half moon phases in the lunar cycle, the moon appears as a semicircle in the sky.

The half moon phases are known as the first quarter moon and the third quarter moon, depending on which side of the moon is illuminated. These phases mark the halfway point between the new moon and the full moon, and they are important for tracking the progression of the lunar cycle.
