What am I supposed to do in Shape Assembly?

One face of the drawn solid is missing, shown as a dashed outline. Compare the detached piece options with the gap · its shape, lean and proportions · and tap the piece that completes the figure.

Where do the shapes come from?

They are the classical solids of Euclid’s Elements (c. 300 BC): the cube, pyramid, prisms and octahedron. The reveal after each answer cites the exact definition or proposition.

What skill does this train?

Spatial reasoning: reading a 3-D structure from a 2-D drawing, mentally rotating a detached face, and matching shape, orientation and proportion · the same skills technical drawings and geometry lessons build on.
