**Math Riddle Answer**

You must have figured out the answer by now.

If you have, congratulations are in order. We knew you could do this.

Still, we are going to reveal the answer so you can cross-check your calculations.

Presuming that the square is 1 x 1, we can now determine the base of the triangle to be 1 (as it is of the same length as the square). Now, we need to determine the height.

One important thing to remember is that the ratio of the triangles' heights to their bases will always be the same, which is a characteristic of identical triangles.

The original of the math riddle, Southall said, "The pink triangle's height is equal to that of the little triangle because its base is twice as large. However, since the pink triangle's height is 1/3 of the tiny triangle's height, we know that its height plus the little triangle's height equals 1. Connect it, and we obtain our area as 1/2 x base x height, or 1/2 x 1 x 2/3, or 1/3."

**Hence, ⅓ fraction of the square is colored. **

The answer has been confirmed to be correct by Ed Southall.
