Alyssa is making a paper dragon puppet as part of her family’s Chinese New Year celebration. She lays her tissue paper over the coordinate plane. Then she draws figure WXYZ for one of the dragon’s eyes. To make the other eye, she reflects figure WXYZ across the x-axis to form the image, figure W9X9Y9Z9 What are the coordinates of the vertices of figure W9X9Y9Z9? Picture It You can draw the image in the coordinate plane. In this case, the x-axis is the line of reflection. flip x y O 2 52225 2 5 W X Y X’ Y’ Z’ W’ Z line of reflection 25 22 Model It You can now identify the coordinates of the vertices of the image. Make a table to compare corresponding vertices. WXYZ W(23, 4) X(21, 4)Y(22, 1)Z(24, 3) W9X9Y9Z9 W9(23, 24) X9(21, 24) LESSON 2 Work with Single Rigid Transformations in the Coordinate Plane
