Answer: Mathematically, it is impossible to add five matches to six matches to result in nine matches.Logically, however, you can add five matches to six matches to make nine if one match is on fire, then you set that match on another match, and eventually both of those matches that were on fire burn themselves into ashes, leaving you with only nine unlit matches left.Answer: You lay out the 11 matches so they spell the word NINE.
Nine, as a n-gon can be cut in n-2 triangles.
Because the sum of the sides of three triangles is nine... Placing three triangles together so they all touch effectively removes four of the total number of sides - leaving five.
you cant.
A nine sided shape has 7 triangles

Nine goals, but those nine goals have been scored in only eight matches. He arrvied at Newcastle in January 2012, and has now scored two gals in each of his last three matches.
There are four triangles in the pyramid. The base triangle that supports the other three counts as THREE straws, one per each of the three sides. But the remaining three triangles also use the base triangle for one of their three sides. That means there are only two additional straws for each of the three remaining triangles. So there are SIX straws total in the three triangles supported by the base one. That's a sum total of NINE (9) unique straws in the pyramid...3 in the base and 2 each in the three supported triangles. ANS.
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.

Divide each of the sides of the triangle into three. Join corresponding points on each pair of sides.
27 triangles. There are 16 one-cell triangles, 7 four-cell triangles, 3 nine-cell triangles, and 1 sixteen-cell triangle.
