Sample practice questions
Easy
1. What is the purpose of a T-square in technical drawing?
To slide along the true edge of the drawing board to produce accurate horizontal lines and align set squares
To draw circles and arcs of a required radius
To transfer measurements along a line
To sharpen pencils to the correct point
Answer: To slide along the true edge of the drawing board to produce accurate horizontal lines and align set squares — A T-square slides along the true (left-hand) edge of the drawing board to produce accurate horizontal lines and to align set squares for vertical and angled lines.
Easy
2. What is the key safety rule for compass and divider points when not actively in use?
They must be capped or pointed away from the body, never left protruding towards where a hand might rest
They should be left open and pointing upward on the desk
They only need to be handled carefully while actively drawing a circle
No special precaution is needed since the points are not sharp
Answer: They must be capped or pointed away from the body, never left protruding towards where a hand might rest — Sharp instrument points present a real puncture hazard, so they must always be capped or pointed away from the body when not actively in use.
Medium
3. Name the drawing instrument with two needle points, used to transfer measurements or step off equal distances along a line.
Answer: dividers — Dividers have two needle points and are used to transfer measurements or step off a series of equal distances without re-measuring with a ruler each time.
