Lesson Plan: Rotational Symmetry Mathematics
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to find the order of rotational symmetry of a geometric figure and its angle of rotation.
Objectives
Students will be able to
- judge whether plane figures have nontrivial rotational symmetry,
- calculate the order of rotational symmetry and angle of rotational symmetry.
Prerequisites
Students should already be familiar with
- rotations, reflections, translations, and dilations,
- similarity and congruence of polygons.
