To determine how many triangles are in the given figure, we need to examine each section of the diagram carefully. Here's a step-by-step approach:

1. First, observe that the square is divided into smaller triangles by the intersecting lines.
2. Let's label the figure for clarity. Assume each side of the square is divided into parts at points where lines intersect, forming smaller triangles inside the square.
3. Count the smallest possible triangles first:
   • There are 8 smaller triangles inside the square created by the intersecting diagonals and median lines.
4. Next, consider combinations of these smaller triangles forming larger triangles:
   • There are 4 larger triangles that are formed by combining two adjacent smaller triangles (e.g., the triangles that span across the center from a corner).

Total triangles = 8 (smallest triangles) + 4 (larger combinations) = 12 triangles.

Therefore, the correct answer is 12.

Thus, the answer is 12.
