You will need 6 matches (make sure they are "dead" ones)
(You could use "lolly sticks" or cocktail sticks or pencils - as long as they are all the same length)
It is obvious that you could use 3 of the matches to construct an equilateral triangle
(equilateral = all 3 sides the same length)
You could use 5 of the matches to construct TWO equilateral triangles.
If you had 7 matches you could construct THREE equilateral triangles.
Using only the 6 matches you must construct SIX equilateral triangles.
(You must not bend or break any of the matches!)
