![]() Reflection in the y-axis: Reflecting a point over the line y-axis, the y-coordinate remains the same, but the sign of x-coordinate is changed. The reflection of the point (x, y) over the line x-axis is the point (x, -y).Įxample: When point Q with coordinates (2, 3) is reflecting over the x-axis line and mapped onto point Q’, the coordinates of Q’ are (2, -3). Reflection in the x-axis: Reflecting a point over the line x-axis, the x-coordinate remains the same, but the sign of y-coordinate is changed. An object and its reflection have the same size and shape, but the figure faces in opposite directions. The original object is called the pre-image, and the reflection is called the image. Line reflection is folding or flipping an object over a mirror line (line of reflection). Transformation Math Examples Line Reflections What are line reflections? Here are the 5 types of transformations in math uses in geometry. Transformation sets the foundation for other areas of study, such as congruence and similarity, the verification of perpendicular segments, the derivation of the equation of a circle etc. Transformations are quite important in many fields, such as the study of art, architecture, anthropology, and many more.
