Recognize, name, describe, compare, classify, sort, and draw two-dimensional geometric shapes (triangles, right-angled triangles, quadrilaterals, rectangles, squares, rhombuses, parallelograms, pentagons, hexagons, and polygons up to 12 sides) based on geometric attributes (number of sides, vertices, angles, parallel/perpendicular sides, right angles, and equal side lengths).
