Do number 1-8 using the graph of y=x as a diagonal line of reflection.Īs a result of this activity, students will learn that some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.Do numbers 1-8 using the y-axis as a vertical line of reflection.Find the coordinates of A, B, and C and A', B', and C'.Mark the midpoint of each of the red segments.Measure the angles where the line of reflection crosses each red segment.Use a straightedge and a red pencil to connect A to A', B to B', and C to C'. If we know the graph of y f (x), we can obtain the graph of its reflection in the x-axis by multiplying the y-coordinate of each point on the graph of y.Locate the images of A, B, and C in the reflected figure.Open the paper and trace that reflection on the front. On the back of the graph paper trace the figure, including A, B, and C.Fold the first sheet of paper along the x-axis for a horizontal line of reflection.In addition, skills to write the coordinates of the reflected images and more are in these pdf worksheets, making them ideal for students of grade 5 through high school. Press hard with your pencil so your figure can be seen through a folded page. Exercises to graph the images of figures across the line of reflection, reflection of points and shapes are here for practice.
