This worksheet is designed for students to practice using angle and segment axioms/postulates prior to starting actual proofs, so students have a solid grasp on how to justify each statement with a valid reason/axiom.

This interactive Geogebra file allows you to use a slider to choose the number of sides on the regular polygon from 3-12 sides. Then it allows you to manipulate side length using a slider. Lastly, you can use a slider to "unfold" the regular polygon into triangles to make a connection between triangle area formula and the regular polygon formula.

Use this Geogebra file to show a proof of Pythagorean Theorem.
