Find all assignments, handouts, & resources for lesson 2 on the Lesson 2 Google Document.

INSTRUCTIONAL GOALS: Students should show they know or learn how to…

• Calculate the interior & exterior angles of a regular polygon
• Use angle measurements to determine which regular polygons tessellate
• Show the lines of symmetry in a 3D shape
• Find the order of rotational symmetry of a 3D shape around each axis
• Use compass directions to find bearings of points in the 2D plane

RESOURCES & LINKS: For help or guidance, students may refer to:

• The MEP chapter 3 on Angle Geometry is the textbook guiding our course. Relevant example problems and definitions are found in the following sections:
  • Section 3.5: Angle Symmetry in Polygons
  • Section 3.6: Symmetry Properties of 3D Shapes
  • Section 3.7: Compass Bearings
• The Art of Problem Solving videos offer worked examples on:
  • Angles in a Polygon, Part 1 and Part 2

• The Math is Fun website gives clear, simple explanations & example problems with answers for these topics:
  • Interior Angles of Polygons & Exterior Angles of Polygons
  • Tessellations
  • 3D Shapes: Polyhedra & Prisms
  • Compass Bearings
