Which term refers to the curve formed at the interior intersection between two or more surfaces?

• A. Inscribe
• B. Right Triangle
• C. Fillet
• D. Work Point

Answer: (C)

Fillet, the curve where surfaces meet, is the term for the rounded interior transition between two or more surfaces. It replaces a sharp corner with a smooth arc that is tangent to the adjacent surfaces, which helps reduce stress concentration and improves manufacturability and surface continuity in design. Inscribe describes drawing a shape inside another figure, not a transition between surfaces; a right triangle is just a type of triangle with a 90-degree angle; a work point is a reference location used for positioning or machining, not a surface-intersection curve.
