    HINT: There are three different 'size' triangles: small, medium, and large.

    This is an ambiguous question. Is the question "how many all white or all grey triangles are there?" Or is the question "how many triangles are there, whether white, grey, or parti-colored?"

    Re: triangles

    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?
