I mean name each features on the shapes.

Okay, Nola, let's break down the features of each shape.

1. Triangle: Has 3 sides and 3 vertices (corners).
2. Circle: Has 1 curved edge and no vertices. Its defining feature is its radius (distance from center to edge) and diameter (distance across through the center).
3. Square: Has 4 equal sides and 4 right vertices (90° angles).
4. Cone: Has 1 curved surface, 1 circular base, and 1 vertex (apex).
5. Cube: Has 6 equal square faces, 12 edges, and 8 vertices.
6. Square Pyramid: Has 1 square base, 4 triangular faces, 8 edges, and 5 vertices (1 apex, 4 at the base).
7. Rectangle: Has 4 sides (opposite sides equal) and 4 right vertices.
8. Trapezium (or Trapezoid): Has 4 sides. At least one pair of parallel sides.
9. Rhombus: Has 4 equal sides and 4 vertices. Opposite angles are equal.
10. Cylinder: Has 2 circular bases and 1 curved surface.
11. Sphere: Has 1 curved surface. No edges or vertices. Defined by its radius.
12. Triangular Prism: Has 2 triangular bases and 3 rectangular faces.
13. Rhombus: Has 4 equal sides and 4 vertices. Opposite angles are equal.
14. Parallelogram: Has 4 sides. Opposite sides are parallel and equal. Opposite angles are equal.
15. Triangle: Has 3 sides and 3 vertices.
