Reflections Quiz

What is a line of reflection?

• A line of reflection is a line that divides an object into two equal halves.

• A line of reflection is a line that rotates an object around it.

• A line of reflection is a line that stretches or compresses an object.

• A line of reflection is a line that acts as a mirror, reflecting an object or shape across it.

What are the properties of reflection?

• Angle of incidence being equal to the angle of refraction, different frequency, different speed

• Angle of incidence being equal to the angle of reflection, different frequency, same speed

• Angle of incidence being equal to the angle of reflection, same frequency, different speed

In the coordinate plane, what happens to the x-coordinate of a point after reflection over the x-axis?

• The x-coordinate of a point remains the same after reflection over the x-axis.

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

• The x-coordinate of a point is negated after reflection over the x-axis.

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