Students will learn essential geometry concepts with the step-by-step Studies in Geometry series of 4 workbooks. Starting with constructing geometric shapes using a compass, ruler, or protractor, students progress through line segments, arcs, circles, triangles, polygons, perpendicular lines, and more. Theorems and postulates are presented informally with short explanations, then are developed using follow-up practice activities. Each workbook also includes a handy glossary of essential concepts and a post-test to check understanding.
