Explanation

Observing means carefully studying the subject’s details, shapes, proportions, and light.

Good drawing relies on how well you notice and translate what you see onto paper.

Explanation

A circle is a basic geometric shape with no edges or corners.

Explanation

Texture refers to how a surface feels or appears to feel — rough, smooth, soft, etc.

It can be actual (felt by touch) or visual (created to look like a texture in art).

Explanation

The 1990s saw a rise in digital media and modern art, which led to a shift away from traditional calligraphy.

Explanation

A vertex is the highest point or the top of a shape, such as in a triangle or cone.

In geometry, it’s where two or more lines or edges meet, often forming an angle.
