What symbol did egyptians artists include in their works?

The symbol that Egyptian artists included in their works is uraeus (royal cobra) symbolizing Lower Egypt. The correct answer is A. This sacred serpent was used to represent ultimate power in Egypt, so as to show someone's royalty, divinity, etc. This is why it was such an important symbol that was often used in art as well as in day-to-day life. Rulers would often wear on the bands on their heads engraved symbols of these snakes, and it was later implemented into art.

lines and shapes are a part of the visual elements which can be played with and used to create a mood or feeling in a composition.

some of the other elements include the pattern, color, tone and texture. all these elements serve together as the construction blocks which are used by the artists to create artwork.

lines are used to form drawings and different shapes are formed when these lines are used in certain lengths or angles. so the artist can play with these elements of art to create and express different moods, thus conveying different  meanings.
