Construction (scale, protractor, compasses)

This CTET Paper 2 Mathematics chapter builds Construction for future Classes VI-VIII maths teachers: ruler (scale), protractor, compasses and set-squares as TLM, constructing a line segment of given length, perpendicular bisector, angles of 60°, 90° and 120°, angle bisector, copying an angle, parallel-lines idea with set-squares, pedagogy of tool-handling and reading-protractor traps, classroom safety and shared geometry kits. Sibling topics Symmetry and Elementary shapes stay one-line contrasts only.
