Constructions, loci, bearings and scale drawings

By the end you’ll be able to

• Construct perpendicular bisectors, angle bisectors, perpendiculars from a point and triangles from given information using ruler and compasses, leaving arcs visible
• Draw loci (a fixed distance from a point or line, equidistant from two points or lines) and shade regions that satisfy several conditions
• Measure and calculate three-figure bearings, including back bearings found with parallel-line angle facts
