Question

A rotation is a transformation that changes a figure's

A. position but not its shape or size
B. size but not its shape
C. shape and size
D. shape but not its size

Answer 1

D. shape but not its size.

A rotation is a transformation that rotates a figure around a fixed point called the center of rotation, by a certain angle.

For example, if you take a triangle and rotate it 90 degrees clockwise around a fixed point, the shape of the triangle changes, but its size remains the same. This is because the length of each side of the triangle remains the same, but their position has changed. Therefore, a rotation changes the position and orientation of a figure, but it does not change its size or shape.

Answer 2

the right answer is A position but not its shape or size
