I recently completed a contract to write twenty-six multiple-choice math problems. Some of the topics included using origin-centered dilations to describe and investigate similarities among geometric objects, analyzing how changes in dimensions affect the perimeters and areas of quadrilaterals and regular polygons, analyzing how a change in the radius affects the circumference and area of a circle, applying the properties of central angles, inscribed angles, and arcs of circles to solve problems, finding the sum of two vectors, and applying congruence and similarity relationships among geometric objects to solve problems. This was a good client to do work for, and I hope for more contracts from them in the future.
