Geometry Reflection

What is the line of reflection in geometry?

• The line of reflection is a line that rotates a figure

• The line of reflection is a line that shrinks a figure

• The line of reflection in geometry is a line that acts as a mirror, reflecting a figure across it.

• The line of reflection is a line that stretches a figure

If a point is reflected over the line y = x, what are the new coordinates?

• (y, x)

• (x, y)

• (y, y)

• (x, x)

What happens to the x-coordinate of a point when it is reflected over the x-axis?

• The x-coordinate of a point remains the same when it is reflected over the x-axis.

• The x-coordinate of a point is squared when reflected over the x-axis.

• The x-coordinate of a point is multiplied by -1 when reflected over the x-axis.

• The x-coordinate of a point is divided by 2 when reflected over the x-axis.

What happens to the y-coordinate of a point when it is reflected over the y-axis?

• The y-coordinate of a point changes sign when reflected over the y-axis.

• The y-coordinate of a point becomes negative when reflected over the y-axis.

• The y-coordinate of a point doubles when reflected over the y-axis.

• The y-coordinate of a point remains the same when reflected over the y-axis.

Define the concept of reflection in geometry.

• Reflection is a dilation in geometry

• Reflection is a rotation in geometry

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

• Reflection is a translation in geometry

If a point is reflected over the line y = -x, what are the new coordinates?

• (y, x)

• (x, y)

• (-y, -x)

• (y, -x)

How does the line of reflection affect the position of a shape?

• The line of reflection changes the position of the shape by mirroring it across the line.

• The line of reflection shrinks the shape

• The line of reflection rotates the shape

• The line of reflection stretches the shape

If a point is reflected over the x-axis, what happens to its y-coordinate?

• The y-coordinate is multiplied by 2.

• The y-coordinate is added to the x-coordinate.

• The y-coordinate is divided by 2.

• The y-coordinate is negated.

If a point is reflected over the y-axis, what happens to its x-coordinate?

• The x-coordinate is squared.

• The x-coordinate is negated.

• The x-coordinate is doubled.

• The x-coordinate is halved.

Explain the difference between reflection in the x-axis and reflection in the y-axis.

• Reflection in the y-axis changes the sign of the y-coordinate.

• Reflection in the x-axis changes the sign of the x-coordinate.

• Reflection in the x-axis changes the sign of both x and y coordinates.

• Reflection in the x-axis changes the sign of the y-coordinate, while reflection in the y-axis changes the sign of the x-coordinate.
