Which is the best definition of a reflection of a figure on the coordinate plane?

• a transformation where exactly half of the points in a figure maintain their distances to a fixed line and are mapped to the opposite side of the fixed line

• a transformation where exactly half of the points in a figure decreases their distances by half to a fixed line and are mapped to the opposite side of the fixed line

• a transformation where all points in a figure maintain their distances to a fixed line and are mapped to the opposite side of the fixed line

• a transformation where all points in a figure decrease their distances by half to a fixed line and are mapped to the opposite side of the fixed line
