Solve a matchstick puzzle.....move 4 matchsticks to make three equilateral..

How can I explain this.. OK think of a radioactive warning sign except the bottom triangle is larger than the top two.

Remove top matchstick and then remove two more from sides ( to leave you a triangle on the left and a triangle on the right.) from the bottom apex move the matchsticks ( 2 ) to make longer sides a larger triangle and then move the remaining matchstick down from centre of this larger triangle to compete bottom row with the single remaining matchstick

Look at the "weel"
You have 2 horizontal matches
You have a point in the middle to make 6 triangels
1. Look now at the little triangel below, move that horizontal match by swinging it in his right corner to follow the line to the point in the middle.
2. Take the upper horizontal match and put it in the left corner to follow that line to thecentral corner. You have now an upside down V
3. You have to make a baseline; take the 2 matches from the outside "circle", the onces who are still in the right and left corner of your first little triangel...
4. You have now 1 big triangel and 2 little onces like "ears in the top!
Mission accomplished!
