Geometry Module 5, Topic A Overview

Student Looking For Books

Topic A leads students first to Thales' theorem (an angle drawn from a diameter of a circle to a point on the circle is sure to be a right angle), then to possible converses of Thales' theorem, and finally to the general inscribed-central angle theorem.  Students use this result to solve unknown angle problems.  Through this work, students construct triangles and rectangles inscribed in circles and study their properties.
