Students need interesting geometric examples to explore for practice with reasoning. Using scissors, the speaker will dissect well-known figures to produce shapes. Using tape, he will assemble shapes from geometrical building blocks. In each instance, he will do the hands-on work in a parallel with the reasoning that yields interesting angle or ratio properties.
