Reflection about line y=x The object may be reflected about line y = x with the help of following transformation matrix First of all, the object is rotated at 45° The direction of rotation is clockwise After it reflection is done concerning xaxis The last step is the rotation of y=x back to its original position that is counterclockwiseExpress reflection in the line y=x as the composition of a rotation followed by reflection in the line y=x ( done by matrices ) Question Express reflection in the line y=x as the composition of a rotation followed by reflection in the line y=x ( done by matrices )Stack Exchange network consists of 178 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers Visit Stack Exchange
$\begingroup$ Reflecting a function along the line y = x is the same as computing the inverse of the function So use a method for computing the inverse of a function to find the reflection about the line y = x $\endgroup$ –Reflections across the line y = x A reflection across the line y = x switches the x and ycoordinates of all the points in a figure such that (x, y) becomes (y, x) Triangle ABC is reflected across the line y = x to form triangle DEF Triangle ABC has vertices A ( Since, we know that the conjugate of a point is the reflection of the point about XAxis In order to be able to use this fact, we will first perform translation (making A as the origin in the new system) and then rotating the coordinate axes in such a way that the line becomes the XAxis in the new coordinate system

Answer (1 of 4) Reflections in the coordinate plane When you reflect a point across the xaxis, the xcoordinate remains the same, but the ycoordinate is transformed into its opposite (its sign is changed) If you forget the rules for reflections when graphing, simply fold your paper along tAnd also, the line x = 2 (line of reflection) is the perpendicular bisector of the segment joining any point to its image Students can keep this idea in mind when they are working with lines of reflections which are neither the xaxis nor the yaxisIf (a, b) is reflected on the line y = x, its image is the point (b, a) Geometry Reflection A reflection is an isometry, which means the original and image are congruent, that can be described as a "flip" To perform a geometry reflection, a line of reflection is needed;

Answer (1 of 4) You really need to draw this out to get a real feel for the answer and what is happening Think of y=2 as a horizontal mirror line Cutting through the yaxis at 2 The point (3,1) will reflect from below the xaxis over the mirror line and end up, above it, keeping the xcoor The point (4, 1) undergoes the following two successive transformations (i) Reflection about the line y = x (ii)Translation through a distance 2 units along the positive xaxis Then the final coordinates of the point areThe resulting orientation of the two figures are opposite

Program of reflection in y Axis;Line segments I end this segment i n over here and T oh this is T oh here are reflected over the line y is equal to negative X minus 2 so this is the line that they're reflected about this dashed purple line and it is indeed y equals negative X minus 2 this right over here is in slopeintercept form the slope should be negative 1 and we see that the slope of this purple line is indeed negativeAnd so we want thes two angles to be the same, so they'll be high fourths or 45 degrees And if we kept drawing that blue line down, for instance, then that would end up having an equation Why is equal to Positive X and then minus one would be the Y intercept there So this would be the equation of the line that would reflect off of the X axis
