Answer:
A segmental pediment is a type of ornamental architectural feature commonly found in classical design. It consists of a curved horizontal section, resembling a segment of a circle, placed on top of a colonnade, doorway, or window. The segmental pediment typically has a convex shape and is often adorned with decorative details like moldings, sculptures, or reliefs.
An unbroken curved pediment, also known as a continuous curved pediment, refers to a pediment design where the curved shape extends without interruption across the entire width of the architectural element it adorns. Unlike a segmental pediment, which is just a portion of a circle, an unbroken curved pediment creates a full semicircular or elliptical shape from one end to the other. It is commonly seen in grand architectural projects, such as elaborate entrances or monumental structures.
The arc of a circle refers to a curved portion of the circumference of a circle. It is formed by connecting two points on the circle with a segment that follows the curved shape of the circle. The arc can vary in length, starting from a very small portion known as a minor arc to the complete circular shape, known as a major arc. In furniture and architectural design, the arc of a circle is often used to create decorative elements like pediments, arches, or circular motifs.
