To determine which statement about the congruency of the trapezoids is correct, you need to consider the effects of each transformation mentioned in the statements:
-
Reflection over the line \(y=x\) would produce a congruent figure, but it will not change the shape or size of the trapezoid, just its orientation.
-
Translation does not change the shape or size of the figure. A translation left 4 units and up 2 units will create a congruent trapezoid.
-
Rotation (whether 270° counterclockwise or 90° counterclockwise) will also not change the shape or size of the trapezoid. Both rotations will produce a congruent figure, as rotation preserves congruency.
Since all transformations stated in the explanations will produce congruent figures, the answer could potentially involve more than one statement being correct. However, the most general statement that can apply to all congruent transformations is translation, reflection, and rotation.
Without more specific geometrical context (like the actual trapezoids), it is challenging to determine which specific transformation made the trapezoids congruent.
However, since the question requests a specific correct statement, if I had to choose one based on the simplicity of explanation, I would go with:
Statement #2 is correct: "The trapezoids are congruent because ABCD was translated left 4 units and up 2 units."
This is because translation is a straightforward method to confirm congruency without changing orientation.
