On the Subject of Slipping Triangles

No, you’re not ice skating.

Please see Appendix 1PP1NG for identifying modules in the Triangles family.

This module will have 9 triangles on it. Each triangle will be coloured green, blue, or violet. To solve the module, all valid triangles must be pressed. Pressing an invalid triangle will cause a strike. If no more valid triangles are present on the module after pressing a triangle, the module will solve. Note that triangles turn off when pressed, regardless of validity.

Identifying valid triangles:

Each triangle will be present in exactly two of the sets below:

Valid triangles are those whose sets match in content, considering off as a colour as well.
