Teaching guide
Identify the conditions for triangles and other common shapes to be congruent or similar, including shapes formed by transformations.
Sort and name 2D and 3D shapes by their properties (sides, angles, faces), then build up to perimeter (add the sides) and area (cover with unit squares).
Generated and checked in code, so it is correct.
Confusing perimeter and area, and judging a shape by its orientation rather than its properties.
