Intelligence Test

Now there are loads of ways of test your intelligence but this  is a great starter for a shape and space Maths lesson. Let’s see how intelligent you are, how many triangles do you see? This would make a great plenary to a Maths lesson too!

    What’s the answer

  2. John willis on said:

    There are 14 triangles. The obvious 9 triangles. The triangle which encases all the triangles, which counts for 1. The top 4 triangles which counts as 1. The 4 left bottom triangles which count for 1. The bottom 4 right triangles which count for 1. And the word “triangles” in the sentence which counts for 1. That equals 14

  3. Aurora on said:

    I agree with John, 14 is the correct answer.

  4. Vivek Kandathil on said:

    There are 13 total triangles: the whole triangle (1), each small one (9), and the 3 triangles that contain 4 small triangles.

  5. bigdog on said:

    there are 10 triangles 1 large and 9 inside

  6. bigdogdc on said:

    there are 10 triangles 1 large triangle and 9 inside that, 1 at the top, 3 in the middle and 5 at the bottom.

  7. J Hopkln on said:

    Only an english major would say 14. Word tricks can be funny but not mathematical or tests of intelligence. Cleverness perhaps. 13 is the correct answer.

  8. greg on said:

    NO, there are 15. look at the overlapping lower ones.

  9. Billy Singleton on said:

    There are thirteen triangles. The whole triangle plus the obvious nine plus the top, bottom left and bottom right triangles each containing four of the small triangles. Fourteen is incorrect…for one reason it is not one of the options. And it would be silly to consider a word a triangle.
