a student is given two images of a rectangle. the second rectangle is in the same orientation but has moved 5 units to the right on a coordinate plane. what type of transformation has occurred?
enlargement
rotation
reflection
translation

Explanation:

• Enlargement: Changes the size of a figure, which is not the case here as the rectangle just moved.
• Rotation: Involves turning a figure around a point, but the rectangle's orientation is the same (no turning).
• Reflection: Creates a mirror - image of a figure, which is not described in the problem.
• Translation: A transformation that slides a figure. Moving 5 units to the right is a sliding motion (translation).

Answer:

Translation
