Hello, user!
I will try to answer the question.
How many triangles (whites and grays) in total there in the following figure?
Code:* / \ * - * - * - * \ /#\#/#\ / * - * - * / \#/#\#/ \ * - * - * - * \ / *
There are 6 white triangles.
There are 6 gray triangles.
There are 12 triangles in total.
If the question is "How many triangles (of any size)?"
. . then why bother with colors?
