Explanation

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

Explanation

A square box that stands out in a design draws attention and becomes the focal point.

The focal point is the center of interest in a composition.

Explanation

A set square is used to construct right angles (perpendiculars) in geometry.

It typically has angles of 90°, 45°, and 60° for constructing perpendicular lines.

Explanation

0° – Zero angle (no turn)

Less than 90° – Acute angle

Exactly 90° – Right angle

Between 90° and 180° – Obtuse angle

Exactly 180° – Straight angle

Between 180° and 360° – Reflex angle

Exactly 360° – Full rotation / Complete angle

Explanation

Op Art (Optical Art) is an art style that uses patterns, shapes, and colors to create optical illusions.

It tricks the eye into seeing motion, warping, or depth that isn't actually there.

Explanation

When warm, moist air inside the car meets the cold glass, condensation forms.

This happens because the glass surface is cooler than the dew point of the moist air.

Explanation

Stippling is a shading technique that uses dots to create texture, depth, and tone.

The density and placement of the dots determine the darkness or lightness of the area.

Explanation

Tertiary colors are made by mixing a primary color with a secondary color (e.g., yellow + green = yellow-green).

Yellow-orange, red-orange, yellow-green are typical examples of tertiary (intermediate) colors.

Explanation

Rough is an example of texture, which refers to the surface quality of an object or artwork.

Texture can be tactile (physical) or visual, and "rough" describes a tactile texture.

Explanation

Visual balance is achieved when all parts of a composition seem to have equal weight, creating a sense of stability.

It is a principle of design that ensures no part of the artwork feels too heavy or too light compared to the rest.
