A series of slides showing how to do the various constructions. Includes perpendicular bisectors, angle bisector, ASA,SSS SAS triangles aswell as some loci. I wouldn't use these as a lesson, maybe would give it to pupils for revision or have it ready to pinch slides out of when i needed them. Hope you find it useful
