This is an icosahedron, a 3D figure with an exterior comprised of only equilateral triangles! (you saw Mr.Abedin's origami version of it earlier). Click and drag the slider and see what happens...
Recall the example 3D pentomino piece from the Isometric and Orthographic Drawing Activity. Here, these drawings are shown together with one possible 2D net of the shape (on the right).
Paste a screenshot of your Isometric and Orthographic drawings of the 3D pentomino you modeled in the previous activity. Then, use that info to create a possible 2D net of the shape.
