Web20. Another way. To reflect along a line that forms an angle θ with the horizontal axis is equivalent to: rotate an angle − θ (to make the line horizontal) invert the y coordinate. rotate θ back. Further, y = m x implies tan θ = m, and 1 + m 2 = 1 cos 2 θ . Then, assumming you know about rotation matrices, you can write. WebReflect over the y-axis: When you reflect a point across the y -axis, the y- coordinate remains the same, but the x -coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y -axis, and B' is 5 horizontal units to the left of the y -axis. The reflection of the point ( x,y) across.
