rectangular pyramid net 3d model

A 3D math manipulative of a rectangular pyramid net. The base is a clear rectangle with a 2:1 length-to-width ratio (obviously elongated). Four isosceles triangles are attached to each edge of the rectangle. The two triangles on the long edges are shorter in height than the two triangles on the short edges, ensuring they would meet at a single point if folded. Low-poly, clean edges, flat 2D layout, high-contrast colors for each face
