Correct answer: D
To determine the number of triangles, we identify the distinct triangular shapes formed by the intersection of the lines.
Triangle Analysis
Triangle ADE: This is the smaller triangle formed at the top of the figure by vertices A, D, and E.
Triangle ABC: This is the large outer triangle formed by vertices A, B, and C.
By examining the figure, these are the only two complete triangular shapes formed by the lines provided.
