What is the result of reflecting a shape over a line?

• The shape rotates 180 degrees

• The shape creates a mirror image across the line

• The shape becomes larger or smaller

• The shape moves to a new position without rotating

How is the angle of rotation determined in a geometric rotation?

• By the size of the shape

• By the distance the shape moves

• By measuring the angle from the center of rotation to a point on the shape before and after the rotation

• By the number of times the shape flips over

How can you identify a dilation among transformations?

• By finding the line of reflection

• By locating the center of rotation

• By observing a change in size while maintaining shape proportions

• By tracking the movement of the shape along a surface
