For example, when reflecting the point (2,5) over y=x it becomes (5,2) This is very simple, but why does it work?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 (2, 2), B (6, 5) and C (3, 6) Triangle DEF has vertices D (2, 2), E (5, 6), and F (6, 3) This concept is new to me I am doing a university level class and the way this class is presented is very theoretical that I even struggle to read

or y = x (2, 2) (4, 4) (5, 5) Just plotting a few of these coordinates will make sure that you always reflect in the correct mirror line The only other issue is to make sure that your reflection is at 90 degrees to the line, and it's the same distance both sides Other than that, you're good to go Here's some videos to helpThis is a KS3 lesson on reflecting a shape in the line y = x using Cartesian coordinates It is for students from Year 7 who are preparing for GCSE This page includes a lesson covering 'how to reflect a shape in the line y = x using Cartesian coordinates' as well as a 15question worksheet, which is printable, editable and sendableYou can use a formula When you reflect over xaxis the coordinates are (x,y) and when you reflect over the yaxis the coordinates are (x,y If you want to reflect over y=x then the coordinates are (y,x) If you want to reflect over y=x the coordinates are (y,x) Comment on Caylen Jang's post "You can use a formula
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 = mx implies tanθ = m, and 1 m2 = 1 cos2θ Then, assumming you know about rotation matrices, you can writeBig Ideas A function maps a set of inputs (a domain) to a set of outputs (a range), and each element of the domain is related to exactly one element of the range An inverse of a function maps the outputs back to their corresponding inputs, and hence the range of a function is the domain of the inverse The graph of an inverse of a function is a reflection of the function across the line y=xHow To Given a function, reflect the graph both vertically and horizontally Multiply all outputs by –1 for a vertical reflection The new graph is a reflection of the original graph about the xaxis Multiply all inputs by –1 for a horizontal reflection The new graph is a reflection of the original graph about the yaxis

Key Points A vertical reflection is given by the equation y=−f (x) y = − f (x) and results in the curve being "reflected" across the xaxis A horizontal reflection is given by the equation y=f (−x) y = f (− x) and results in the curve being "reflected" across the yaxis Other Lines A reflection can occur across any line, it is not limited to the three lines discussed previously The example below demonstrates a reflection that is not specific to the axes or the line y = x Examine the drawing below to see the relationship between the coordinates of the preimage and imageCheck all that apply 1 Every line connects two vertices 2Every line connects the midpoints of 2 sides 3Every line bisects a vertex angle 4Every line bisects a side 5Every line is perpendicular to a side 3 Every line bisects a vertex angle 4 Every line bisects a side 5 Every line is perpendicular to a side

This is all about reflections The preimage , quadriateral ABCD, can be reflected through the axes, the line y=x, or the line y=x Begin with the reflection thoughWhen we reflect a point in the xy plane over the line y = x, the image has the x and ycoordinates switched So here, (2, 5) and (5, 2) are reflected images of each other over the line y = x In other words, we swap the place of the xcoordinate and the ycoordinate, that's the effect of reflecting over this particular lineWhich reflection of the point will produce an image at the same coordinates, (0, k)?

The reflection of the point (x, y) across the line y = – x is (y, x) Reflection in a Point A reflection point occurs when a figure is constructed around a single point known as the point of reflection or centre of the figure For every point in the figure, another point is found directly opposite to it on the other sideTo reflect points across the line {eq}y=x {/eq}, we must swap the coordinates and change their signs To see why this works, consider the first and third quadrants The reflection about the line Y=X is equivalent to the reflection along the Xaxis,followed by counter clockwise rotation by θ degreesFind out the value of θ

Reflection can be found in two steps First translate (shift) everything down by b units, so the point becomes V=(x,yb) and the line becomes y=mxThen a vector inside the line is L=(1,m)Now calculate the reflection by the line through the origin,A shape can be reflected in the line y = −x If point on a shape is reflected in the line y = −x both coordinates change sign (the coordinate becomes negative if it is positive and vice versa) the xcoordinate becomes the ycoordinate and the ycoordinate becomes the xcoordinate When you reflect a point across the line y = x, the xcoordinate and the ycoordinate change places and are negated (the signs are changed) The reflection of the point (x, y) across the line y = x is the point (y, x) P(x,y)→P'(y,x) or r y=x (x,y) = (y,x) The reflection of the point (x, y) across the line y = x is the point (y, x)
