Assignment 8:



Assignment 8A'B' is the image of AB when the y-axis is the mirror line and A"B" is the image of AB when the x-axis is the mirror line. Write down the coordinates of A'B' and A"B".Compare these coordinates with the coordinates of AB. Write a generalization about what happens to the coordinates of a point when it is reflected across the y-axis and similarly the x-axis.The following figures are transformed under reflection in XY. Trace a copy of each figure and using geometrical instruments, construct the image of each figure and label the image appropriately.What happens to the coordinates of a point when it is rotated:90 degrees counterclockwise?180 degrees counterclockwise?270 degrees counterclockwise?Copy the following figures on graph paper. Draw and label the image of each figure under rotation about the origin through the angle indicated.90 degrees clockwise.270 degrees counterclockwiseCopy the following figures on graph paper. Draw the images of each figure under rotation as instructed.Describe what happens when you compose two reflections over two parallel lines. What single transformation is this equivalent to and how does it relate to the distance between the two parallel lines?Describe what happens when you reflect an object twice over two intersection lines. This is equivalent to what single transformation? How is it related to the acute angle between the two lines? ................
