TSA 2D–3D Spatial Test

Pentagon Frustum · Isometric · Face Labels
0 / ?
3D (left): Isometric view from above. The marks the reference face — always facing you. Letters label the visible faces.
Net (right): Same shape unfolded flat. Numbers label every face. More numbers than letters — only visible 3D faces get a letter. Type each letter's net number.
3D — isometric view from above ·
2D Net — all faces numbered (net has more numbers)

Type the number from the net that matches each 3D letter. Not all net numbers appear in the 3D view.

✓ All correct!

Labels on faces (surfaces) · Net: BFS unfolding · 3D: isometric from above · view angle varies each game
