Learning activities:

  1. Angle Exploration:
    • Use a protractor to measure and classify various angles.
    • Investigate the relationships between complementary and supplementary angles.
  2. Polygon Properties:
    • Calculate the sum of interior angles in different polygons.
    • Explore how the measure of each interior angle relates to the polygon’s type.
  3. Area Calculations:
    • Practice using area formulas for triangles, rectangles, squares, and circles.
    • Work through examples that involve angles in the context of area calculations.
  4. Geometric Construction:
    • Engage in hands-on activities to construct triangles and quadrilaterals, paying attention to angle measures.
    • Explore how changing angle measures affects the resulting figure’s properties and area.
