Let's count the straight lines in the given figure:

1. **Vertical Lines**: None in this figure.
2. **Horizontal Lines**: There is 1 horizontal line near the middle.
3. **Diagonal Lines**: There are 2 diagonal lines forming the sides of the triangle.
4. **Additional Lines**: There is 1 line parallel to the base inside the triangle.

Thus, the total number of straight lines in the figure is:

\[
2 \, \text{(diagonal)} + 1 \, \text{(horizontal at the base)} + 1 \, \text{(horizontal inside)} = 4 \, \text{straight lines}
\]
