Question

in the diagram the smaller triangle is an image of the larger triangle. a) name the angle in the image that corresponds to $\angle f$ in the preimage. a) $\angle f$ is the preimage of $\angle$ dropdown with options $f$, $g$, $d$

Explanation:

a) In a transformation, the image of an angle retains the corresponding vertex label with a prime mark. Since ∠F is in the preimage, its image is ∠F'.
b) Corresponding sides connect corresponding vertices: CD ↔ C'D', CF ↔ C'F', FD ↔ F'D'.

Answer:

a) ∠F'
b) CD and C'D', CF and C'F', FD and F'D'
