Alex Phipps Ch6 Geogebra Project;Click and drag the blue dot and watch it's reflection across the line y=x (the green dot) Pay attention to the coordinates How do they relate to each other?Apply a reflection over the line x=3 Since the line of reflection is no longer the xaxis or the yaxis, we cannot simply negate the x or yvalues This is a different form of the transformation Let's work with point A first Since it will be a horizontal reflection, where the reflection is over x=3, we first need to determine the
A reflection (or flip) is one kind of transformation The reflection of a point is another point on the other side of a line of symmetry Both the point and its reflection are the same distance from the line The following diagram show the coordinate rules for reflection over the xaxis, yaxis, the line y = x and the line y = x Scroll downMore A point and its reflection over the line x=1 have two properties their ycoordinates are equal, and the average of their xcoordinates is 1 (so the sum of their xcoordinates is 1*2=2) So (2,3) reflected over the line x=1 gives (22,3) = (4,3) Comment on Ian Pulizzotto's post "A point and its reflection over the line x=1 haveDefining key concepts ensure that you can accurately define key ideas, such as the three types of reflections across the y or x axes, around the origin, or across the y=x line Additional Learning

For this type of reflection, all you have to do is switch the x and y values if a point is (4,2), then the inverse is (2,4) If you begin with a function y=sqrt (x), there are many different lines you could reflect this function across, but only reflecting over y=x will give you the inverse ofSo, the first step is using the dot product to get a vertical vector that will be used in step 2 With step 1 my partial formula is 2 × ( a ( − a →) ⋅ n → × n) mind the change of sign of a → above, we "flipped" it Then in step 2, I can write − a → 2 × ( a ( − a →) ⋅ n → × n) Now, I A good diagram for these types of questions is useful From the diagram we see the object point ( − 2, −5) is mapped to (x',y') by a reflection in the line X = 2 we note (1) the ycoordinate is unaffected (2) for reflections the distance from the line of reflection to the object is equal to the distance to the image point ∴ a = 2 2

While reflecting about the line y=x, we get the reflected points by swapping the coordinates So, Option 3 is correct Now, the rule for reflecting a point about the line y= x is While reflecting about the line y= x, we get the reflected points by multiplying '1' with the swapped coordinates So, Option 2 is correct The reflection of the point (a, b) across the line y = x is (b, a) By following these rules, you can reflect any line or figure across any of the three most common lines of reflectionWhen 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

Reflection Across Y=X When reflecting over the line y=x, we switch our x and y, and make both negative Reflection Over Y = X In order to define or describe a reflection, you need the equation of the line of reflectionReflection about the line y = x Reflecting over Any Line When we look at the above figure, it is very clear that each point of a reflected image A'B'C' is at the same distance from the line of reflection as the corresponding point of the original figure In other words, the line x = 2 (line of reflection) lies directly in the middleReflect over the xaxis 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 the xaxis (the line of reflection) to see where the new figure will be located Or you can measure how far your points are away
