Inscribe Semicircle In Square by Geometric Construction (slide show)

As an exercise in geometry: Inscribe a semicircle in a square using compasses and ruler. A slideshow showing the steps of construction using Geogebra and Dr Geo dynamic geometry software. Exercises on slide 9. Includes novel examples and self similar (spiral) constructions. Basic use of compass and straightedge to draw geometric constructions is advised as a prerequisite topic. This topic should encourage you to take a fresh look at familiar shapes, to ask questions, to do experiments with geometry and mathematics, and to prove your results.
