Arch vs. Arc: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Updated on October 12, 2023
Arch is primarily a curved structure supporting weight above, while Arc refers to a portion of a circle or curve.

Key Differences

Arch is often used in the context of architecture and construction. It's a structure with a curved shape, usually at the top, which can bear the weight of materials above it. Arc, on the other hand, refers to a segment or part of a circle or any other curve.
