Web10. máj 2024 · The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4). Notice that the x-coordinate for both points did not change, but the ... WebReflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point. E.g. Triangle P P has been reflected in the line x=4 x = 4 to give Triangle Q Q. Triangle P P is the object and Triangle Q Q is the image.
