数图形。图片中共有多少个三角形？---**Chart/Diagram Description:** * **Type:** Geometric diagram/pattern. * **Main Elements:** * The diagram consists of multiple straight lines forming triangles. * There are a total of eight equilateral triangles. * The triangles are arranged in two horizontal rows. * The top row contains four triangles pointing downwards. These triangles share vertical sides. The bases of these triangles form the top edge of the pattern. * The bottom row contains four triangles pointing upwards. These triangles also share vertical sides. The bases of these triangles form the bottom edge of the pattern. * The vertices of the bottom-pointing triangles in the top row align with the bases of the top-pointing triangles in the bottom row, forming a shared horizontal line in the middle of the pattern. * The left-most and right-most vertical sides are not shared by triangles pointing in opposite directions. * The overall shape of the pattern is a hexagon elongated horizontally, with some internal lines forming the individual triangles. * **Other Relevant Text:** None present in the image. * **Mathematical Formulas/Chemical Equations:** None present in the image. * **Table Content:** None present in the image.
