[10000印刷√] reflection across the line y=x formula 812148
A reflection is a transformation representing a flip of a figure Figures may be reflected in a point, a line, or a plane When reflecting a figure in a line or in a point, the image is congruent to the preimage A reflection maps every point of a figure to an image across a line of symmetry using a reflection matrixY = x Triangle XYZ is reflected across the yaxis, and X = (4, 5) What are the coordinates of X' ?A point reflection is just a type of reflection In standard reflections, we reflect over a line, like the yaxis or the xaxisFor a point reflection, we actually reflect over a specific point, usually that point is the origin $ \text{Formula} \\ r_{(origin)} \\ (a,b) \rightarrow ( \red a , \red b) $ Reflect Function About Y Axis F X Expii Reflection across the line y=x formula
