Question

Please help me understand the meaning of the phrase "coloured triangles of floating three-dimensional geometric figures" in the following sentence (not available online):

In the game, your task involves arranging the coloured triangles of floating three-dimensional geometric figures in order to match the completed design shown at the top of the screen.

The sentence is from the description of the game TRIZ. You can watch the gameplay here.

Does the phrase mean that triangles are made of geometric figures?

Thank you for your time.

Answer 1

A triangle is a 2-dimensional shape.

The sides of most 3-dimensional shapes are themselves 2-dimensional shapes. For example, a tetrahedron has 4 sides, all triangles. Various other shapes also have sides that are triangular, including triangular prisms and triangular pyramids.

"your task involves arranging the coloured triangles of floating three-dimensional geometric figures"

This means that you must arrange the 2-dimensional triangles (which are coloured) that make up 3-dimensional shapes.

To put it another way, it appears that you make 3D shapes out of 2D shapes. Like building a piece of flat-pack furniture - you start out with flat pieces, but in the end you have something 3-dimensional.
