Question

determine if the triangles are similar. if so, state the postulate or theorem and write the similarity statement.

Explanation:

Step1: Calculate the ratios of corresponding sides

Calculate $\frac{EF}{BC}=\frac{8}{4} = 2$ and $\frac{FD}{CA}=\frac{12}{3}=4$.
Since $\frac{EF}{BC}
eq\frac{FD}{CA}$, the sides are not in proportion.

Answer:

The triangles are not similar.
