Midterm Reviewer: Drawing Instruments, Alphabet of Lines, and Geometric Construction Drawing Instruments and Their Uses \* T-square: Used for drawing horizontal lines. \* Triangle: Used for drawing vertical and angled lines. \* Compass: Used for drawing circles and arcs. \* Protractor: Used for measuring and drawing angles. \* Ruler: Used for measuring straight lines. \* Eraser: Used for removing pencil marks. \* Technical pen: Used for inking lines. \* Drawing board: Provides a stable surface for drawing. Alphabet of Lines \* Visible line: Represents edges visible in the view. \* Hidden line: Represents edges not visible in the view. \* Center line: Indicates the axis of symmetry of an object. \* Dimension line: Shows the location and extent of dimensions. \* Extension line: Extends from the object to the dimension line. \* Section line: Indicates the material removed in a sectional view. \* Phantom line: Represents alternate positions or moving parts.
