Firstly, the square is divided into four small squares (divided by the middle line), and it can be counted that some of them have 1 1 triangles, so there are11x 4; Then, consider that the male parts of two small groups form a triangle in a rectangle, and each rectangular group has four triangles composed of male parts, so there are 4x4. So * * * has 1 1x4+4x4=60 triangles.
