Geometric Construction Skills

Learners develop the practical skills to draw accurate geometrical shapes using only a compass, ruler, and pencil. Focus is given to constructing triangles, perpendicular bisectors, angle bisectors, inscribing and circumscribing polygons. Construction skills are tied to real-life tasks in design, engineering, and technical drawing.

Learning Outcomes:

The learner should be able to:

• draw perpendicular and parallel lines.
• construct perpendiculars, angle bisectors, mediators and parallel lines.
• use a pair of compasses and a ruler to construct special angles. (60⁰,30⁰ ,45⁰)
• describe a locus.
• relate parallel lines, perpendicular bisector, angle bisector, straight line and a circle as loci.
• draw polygons.
• measure lengths and angles.
• construct geometrical figures such as triangle, square, rectangle, rhombus, parallelogram.
• Inscribe and circumscribe polygons.
