Refelction in Geometry

What is the result of reflecting a triangle over the x-axis?

• The result of reflecting a triangle over the x-axis is a new triangle with its y-coordinates unchanged.

• The result of reflecting a triangle over the x-axis is a new triangle with its z-coordinates negated.

• The result of reflecting a triangle over the x-axis is a new triangle with its y-coordinates negated.

• The result of reflecting a triangle over the x-axis is a new triangle with its x-coordinates negated.

If a shape is reflected over the y-axis, what will be the change in its coordinates?

• The y-coordinate of each point is multiplied by -1, while the x-coordinate remains the same.

• The x-coordinate of each point is multiplied by -1, while the y-coordinate remains the same.

• The x-coordinate of each point is divided by -1, while the y-coordinate remains the same.

• The x-coordinate of each point is added by 1, while the y-coordinate remains the same.
