It is a right angle
During the moon's crescent phases, the earth is at the vertex of an acute angle formed with the sun and moon. Another way to look at it is that during the crescent phases, the moon is always less than 90° away from the sun in our sky. Also, it rises and sets within 6 hours of the sun.
They are at 'right-angles', with the Earth at the corner of the right angle.
During spring tides, the Earth, Moon, and Sun are aligned in such a way that their gravitational forces combine to create higher high tides and lower low tides. This alignment occurs during the full moon and new moon phases when the Earth, Moon, and Sun form a straight line.
During a new moon phase, the moon is not visible from Earth as it is located between the Earth and the sun. The Earth experiences a solar eclipse when this occurs. During a full moon phase, the entire sunlit side of the moon is visible from Earth. The Earth experiences a lunar eclipse when this occurs. Throughout the different phases, the moon exhibits varying amounts of illumination and visibility from Earth.
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.

its the angle of the earth, and the gravitational pull.

The moon changes phases because different portions of the moon are illuminated by the sun, as seen by observers on Earth. The angle formed by the sun, the Earth, and the moon, is constantly changing as the Earth orbits the sun and the moon orbits the Earth.
During spring tides, the Earth, Moon, and Sun are aligned in such a way that their gravitational forces combine to create higher high tides and lower low tides. This alignment occurs during the full moon and new moon phases when the Earth, Moon, and Sun form a straight line.
Imagine an angle, with the Earth at the vertex and the sun and moon on the two rays. -- New Moon . . . the angle is zero. -- Crescent phases . . . the angle is acute. -- First Quarter and Third Quarter . . . the angle is 90°. -- Gibbous phases . . . the angle is obtuse. -- Full Moon . . . the angle is 180°.
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.
During a new moon phase, the moon is not visible from Earth as it is located between the Earth and the sun. The Earth experiences a solar eclipse when this occurs.

This phase occurs roughly a week after the new moon and is part of the lunar cycle.
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.
The angle of a crescent moon is determined by the relative positions of the Sun, Earth, and Moon in space. It is a result of the sunlight reflecting off the Moon, with the angle changing as the Moon orbits the Earth and moves in relation to the Sun.
The moon is sometimes visible during the daytime because its position in its orbit around the Earth causes it to be in the sky at the same time the sun is. Depending on its phase, angle, and position relative to the sun and Earth, the moon can be visible during the day.
