alleryWhat can an unmarked straightedge be used for in a construction?
AMeasuring a length in centimetres
BDrawing a line segment between two points
CDrawing a circle around a point
DMeasuring an angle in degrees
Answer & Solution
Correct answer: B. Drawing a line segment between two points
1. A straightedge has one edge and no markings.
2. It can only join two points with a line segment or extend a segment.
3. It cannot measure length or draw circles; the compass draws circles.
