What happens to the coordinates of a point (x, y) when reflected over the x-axis?

• The coordinates become (x, y)

• The coordinates become (-x, y)

• The coordinates become (x, -y)

• The coordinates become (-x, -y)

What is the difference between reflection and rotation?

• Reflection flips a shape over a line, while rotation turns a shape around a point.

• Reflection rotates a shape around a point, while rotation flips a shape over a line.

• Reflection and rotation are the same; both involve moving a shape without changing its size.

• Reflection changes the size of a shape, while rotation keeps the size the same.

What is the definition of Reflection in geometry?

• Reflection is a transformation that flips a figure over a line, creating a mirror image.

• Reflection is a transformation that rotates a figure around a point.

• Reflection is a transformation that enlarges a figure while maintaining its shape.

• Reflection is a transformation that translates a figure along a straight path.

Can a reflection change the size of a shape?

• Yes, a reflection can change the size of a shape.

• No, a reflection does not change the size or shape of the figure.

• A reflection can only change the color of a shape.

• A reflection can distort the shape but not the size.

What is the line of reflection?

• The line over which a figure is reflected.

• A line that divides a shape into two equal parts.

• A line that connects two points in a figure.

• A line that represents the axis of symmetry.

What is the relationship between the original figure and its reflection?

• The original figure and its reflection are congruent.

• The original figure is larger than its reflection.

• The original figure and its reflection are similar but not congruent.

• The original figure and its reflection are different shapes.

What happens to the coordinates of a point (x, y) when reflected over the y-axis?

• The coordinates become (x, -y).

• The coordinates become (y, x).

• The coordinates become (-x, y).

• The coordinates become (y, -x).

What is a real-world example of reflection?

• A mirror image of a person is an example of reflection.

• The way light bends when passing through a lens.
