What is the rule that describes a reflection across the line y = x
What is the rule that describes a reflection across the line y = x-A reflection across xaxis is nothing but folding or flipping an object over the x axis The original object is called the preimage, and the reflection is called the image If the preimage is labeled as ABC, then t he image is labeled using a prime symbol, such as A'B'C' An object and its reflection have the same shape and size, but the figures face in opposite directions14 · Reflection in a Line A reflection over a line k (notation r k) is a transformation in which each point of the original figure (preimage) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line Remember that a reflection is a flip Under a reflection, the figure does not change size
