Question

use the image to answer the question. bella wants to use rigid transformations to show that △ghi ≅ △lkj to illustrate the sss triangle congruence criterion. which of the following could she do first? (1 point) translate △ghi along a vector that takes point i to point l. translate △ghi along a vector that takes point g to point l. translate △ghi along a vector that takes point i to point k. translate △ghi along a vector that takes point g to point j.

Explanation:

To show $\triangle GHI\cong\triangle LKJ$ using SSS (Side - Side - Side) congruence criterion with rigid transformations, we first need to align one of the vertices of $\triangle GHI$ with a corresponding vertex of $\triangle LKJ$. Translating $\triangle GHI$ along a vector that takes point $G$ to point $L$ is a good first - step as it starts to align the two triangles for further rigid transformations (like rotations or reflections if needed) to match all the corresponding sides.

Answer:

Translate $\triangle GHI$ along a vector that takes point $G$ to point $L$.
