Question

While sorting shapes, Jamie accidently mixed up two groups. Before the mix-up, each group contained 3 shapes: two polygons and the solid they form together. If so, help Jamie sort them back into the two original groups.

Answer 1

Each solid among the given shapes is made of two other planar shapes.

A cylinder is made of a rectangle wound around 2 circles.


So, the cylinder (2) can be grouped together with the rectangle (3) and the circle (5).

Similarly, a square pyramid is made of 4 conjoined triangles with a square at their base.


So, the square pyramid (6) can be grouped together with the square (4) and the triangle (1).

Hence, the two groups will be: (1, 4, 6) and (2, 3, 5)
