Name each shape: Prisms and Pyramids worksheet with various 3D geometric figures.

Final Answer:
Cube, Tetrahedron, Triangular Prism, Pentagonal Prism, Hex Prism, Square Pyramid, Pentagonal Pyramid, Triangular Antiprism (or Triangular Dipyramid), Octahedron (Square Antiprism / Square Bipyramid)

Wait — the task says “Name each shape”, and there are 9 shapes. Let me carefully identify each one in order (row by row, left to right):

1. Green solid with 6 square faces → Cube
2. Black outline: 4 triangular faces, all meeting at a point, base is triangle, 4 vertices → Triangular Pyramid (also called Tetrahedron)
3. Pink solid: two parallel triangles connected by rectangles → Triangular Prism
4. Blue solid: two parallel pentagons connected by rectangles → Pentagonal Prism
5. Purple solid: two parallel hexagons + 6 rectangular sides → Hexagonal Prism
6. Black outline: square base, 4 triangular faces meeting at apex, 5 vertices → Square Pyramid
7. Black outline: pentagonal base, 5 triangular faces → Pentagonal Pyramid
8. Teal solid: two tetrahedra glued on a triangle? Actually, it’s a polyhedron with 6 triangular faces, 5 vertices — that’s a Triangular Bipyramid (also called *dipyramid*), or sometimes called a Triangular Antiprism, but standard name for 6 triangles, 5 vertices is Triangular Dipyramid. However, in many school contexts, this is just called a Triangular Bipyramid. But let’s double-check: It has 6 triangular faces, 5 vertices, 9 edges — yes, that’s the *triangular bipyramid*.

But wait — another possibility: Some curricula call shape #8 a Octahedron only if it's regular (all equilateral triangles). This one looks like two square pyramids glued at the base? No — it has a rhombus-like middle cross-section; actually, looking again: it has 4 triangles on top and bottom? No — better to zoom.

Let me use the zoom tool to verify ambiguous shapes.
