Q

Which of the files listed is tapered on three sides and is used to file acute internal angles?

🔍 Key Concepts

• Cross-sectional shape of files and what areas they can reach • How tapered files are designed to get into tight or sharp inside corners • Difference between files for internal angles vs. outside curves or flat surfaces

💭 Think About

• Which file shape can actually fit into a very sharp inside corner (an acute internal angle) without its sides getting in the way? • If a file is tapered on three sides, what basic geometric shape does that suggest? • For each file name, visualize its cross-section (end view). Which one naturally matches "three sides" and can reach into tight internal angles?

✅ Before You Answer

• Match each file type name (mill, round, square, triangular) with its cross-sectional shape • Identify which shapes can or cannot reach acute internal angles (less than 90°) • Confirm which file type is commonly described as being tapered on three sides in basic tool references
