A Pyramid of Thirteen Triangles
Eighteen matches form a big slanted rhombus with small triangles above its top side and below its bottom side. Some of the partitions inside the rhombus are missing, so there are 8 triangles now (6 small and 2 big). Move 4 matches so that there are exactly 13 triangles, with no loose matches.
All closed equilateral triangles on the board count, both small ones and bigger ones made up of them.
