Dr. Paul Baker, a Catawba College professor of mathematics, attended the Mathematical Association of America's Southeastern Regional Section meeting at the University of Alabama in Tuscaloosa on April 1-2.

At the conference, Baker organized and co-chaired the Special Session on Geometry. During the Geometry Session, Baker also made two presentations. In the first talk, "Sum of Point Angles in Stars," Baker showed that the sum of the point angles in every odd-pointed star polygon on the boundary of a convex figure equals 180 degrees. In the second presentation, "Finding a Solution by Construction," he demonstrated how using Geometer’s Sketchpad to construct a complex figure can greatly simplify a geometric proof.
