This worksheet introduces students to the concepts of central angles, arc measures, minor arcs, and semicircles, and then has them use the concepts to several problems.
Students develop ideas about chords, diameters, and tangents by making direct measurements of segments and angles, and making conjectures about them.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
