In a given square figure $\text{ABCD}$, both main diagonals $\text{AC}$ and $\text{BD}$ are drawn, intersecting each other at point $\text{O}$. Count the total number of triangles formed inside the figure.

Let's systematically count the triangles formed in a square $\text{ABCD}$ with intersecting diagonals $\text{AC}$ and $\text{BD}$ at $\text{O}$:
1. Small individual triangles (single regions):
* $\Delta \text{AOB}$
* $\Delta \text{BOC}$
* $\Delta \text{COD}$
* $\Delta \text{DOA}$
* Total single-region triangles = $4$

2. Large combined triangles (composed of two regions each):
* $\Delta \text{ABC}$ (composed of $\text{AOB}+\text{BOC}$)
* $\Delta \text{BCD}$ (composed of $\text{BOC}+\text{COD}$)
* $\Delta \text{CDA}$ (composed of $\text{COD}+\text{DOA}$)
* $\Delta \text{DAB}$ (composed of $\text{DOA}+\text{AOB}$)
* Total multi-region triangles = $4$

$$\text{Total number of triangles}=4+4=8$$
