· ROTATION RULES Worksheet 17 ROTATION BY 90 ABOUT THE ORIGIN (Use Patty Paper to help you with these!!) PREIMAGE LOCATION REFLECTION IMAGE LOCATION a) Place DEF on the coordinate grid at D(0,4), E(3,4) and F(0,0)Determine the line of reflection The most common lines of reflection are the xaxis, the yaxis, or the lines y = x or y=−x The preimage has been reflected across he yaxis This means, all of the xcoordinates have been multiplied by 1 You can describe the reflection in words, or with the following notation ry−axis(x,y)→(−x,y)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
