What are shown to demonstrate that the triangles are congruent? The rotation is 90 degrees. What is the translation?
To demonstrate that the triangles are congruent when rotated 90 degrees clockwise, the following can be shown:
1. Both triangles have the same lengths of corresponding sides.
2. Both triangles have the same measures of corresponding angles.
3. Both triangles have the same orientation after the rotation.
The translation after a 90-degree rotation would be to move the triangles to the right if the rotation was clockwise or to the left if the rotation was counter-clockwise. The distance of the translation would depend on the size of the triangles and the direction of the rotation.
