technical drawing. 2. Cutting plane lines are thick, broken,intermittent lines with small 90-degree arrowhead . Illustrate how they are shown in solid geometry. (4 marks) (4 marks)

The correct answer is: Cutting plane lines are thick, broken, intermittent lines with small 90-degree arrowheads.<br /><br />In solid geometry, cutting plane lines are used to indicate the plane in which a solid object is being cut or sectioned. These lines are typically represented as thick, broken, and intermittent lines with small 90-degree arrowheads. The arrowheads point towards the direction of the cut or section, indicating the orientation of the cutting plane. This visual representation helps in understanding the orientation and position of the cutting plane in relation to the solid object being sectioned.
