Yes it is
An example of an illuminated object is a light bulb. When turned on, a light bulb emits light, making it an illuminated object.
The Moon is illuminated by the Sun. At full moon, we see the bright part - the illuminated part. At new moon, we see mostly the dark part. (This part is also slightly visible, due to light reflected from the Earth.)

The moon is not a luminous object; it does not generate its own light. The moon is visible to us on Earth because it reflects sunlight. The amount of light reflected depends on the moon's position in its orbit.
An illuminated object is an object upon which electromagnetic radiation from some source is falling. We usually think of "illumination" in terms of light, but it's actually a broader concept. When an airplane is being examined by ground radar, they say that the radar is "illuminating" the target.
An illuminated object reflects light that came from somewhere else. A luminous object emitts its own light.
Luminous objects give off light whereas illuminated objects relfect light, and thus appear to produce light. For example: A lightbulb is luminous because it gives off light whereas the moon is illuminated because it reflects the light of the sun.A luminous object shines with its own light; it produces its own light, like the sun. An illuminated object is lit by some outside source, like a light bulb or something lit up because your car's headlights fall on it at night, such as your garage door.
The size of the illuminated portion of a planet or moon can vary depending on its position relative to the light source, typically the sun. The illuminated portion represents the side facing the light source, while the unilluminated portion is in shadow. This distribution of light and shadow creates phases for the object, such as the lunar phases of the Moon.
A gibbous moon is when the illuminated portion of the moon is more than half but less than fully illuminated. This occurs during the waxing phase after the first quarter moon and before the full moon.
No. Only half of the moon is illuminated at any one time. During a full moon, the half facing Earth is fully illuminated.
The moon is illuminated by the sun.
Yes. A gibbous moon is a three-quarter moon.
