In the first quarter moon, the round portion of the visible moon faces west (forming the letter D when viewed in the northern hemisphere). In the last quarter phase the round portion faces west.
The four faces of the moon are called the Phases of the Moon. They are the New Moon, First Quarter, Full Moon, and Last Quarter.
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
A WANING Moon. An increasing Moon is called a waxing Moon. NB From New Moon to first quarter it is a WAXING CRESCENT Moon From 1sr Quarter to Full Moon it is a WAXING GIBBOUS Moon From Full Moon to Last Quarter it is a WANING GIBBOUS Moon From Last Quarter to next New Moon it is a WANING CRESCENT Moon.
The phase of the moon is called a first quarter or last quarter moon when it appears as a semi-circle. This occurs when the moon is at a 90-degree angle relative to the Earth and the Sun, resulting in half of the illuminated side facing Earth.
When the moon is becoming full, it is called the waxing gibbous phase. It occurs after the first quarter moon and before the full moon, when more than half but not all of the moon's face is illuminated.

New moon, first quarter, full moon and third quarter
A WANING Moon. An increasing Moon is called a waxing Moon. NB From New Moon to first quarter it is a WAXING CRESCENT Moon From 1sr Quarter to Full Moon it is a WAXING GIBBOUS Moon From Full Moon to Last Quarter it is a WANING GIBBOUS Moon From Last Quarter to next New Moon it is a WANING CRESCENT Moon.
The first quarter and last quarter of the moon are each approximately 7 days apart from the new moon and full moon, respectively. Since the full moon occurs about 14 days after the new moon, the first quarter and last quarter phases are roughly 7 days apart from each other. Therefore, the first quarter and last quarter of the moon are about 14 days apart.
first or last quarter
We see a Half Moon illuminated. The name of this phase is called Last Quarter. First Quarter is 1 week before a Full Moon.

Both the 1st Quarter moon and the 3rd (last) Quarter moon can be referred to as the "half moon" since we see half of the sunlit side of the moon.
The periodic changes in the moon's shape are called phases. The moon goes through different phases as it orbits the Earth, including new moon, first quarter, full moon, and last quarter.
