Slide After any of those transformations (turn, flip or slide), the shape still has the same size, area, angles and line lengths. ![]() Translation Shapes are slid across the plane. Three of the most important transformations are: Rotation. Reflection Shapes are flipped across an imaginary line to make mirror images. The translation is in a direction parallel to the line of reflection. Like restricted game pieces on a game board, you can move two-dimensional shapes in only three ways: Rotation Shapes are rotated or turned around an axis. Glide Reflection: a composition of a reflection and a translation. While you got it backwards, positive is counterclockwise and negative is clockwise, there are rules for the basic 90 rotations given in the video, I assume they will be in rotations review. The image is congruent to the original figure. ![]() The result is a new figure, called the image. This reflection maps A B C onto the blue triangle over the gold line of reflection. G.CO.5 - Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, graph paper. You can compose any transformations, but here are some of the most common compositions. What is a reflection A reflection is a type of transformation that takes each point in a figure and reflects it over a line.Compare transformations that preserve distance and angle to those that do not Two of these compositions of reflections therefore equals a rotation by 360° (2180360) around the origin which puts the point back in the exact same spot Therefore, since 100 is a multiple of 2, the final image after 100 compositions is the same as the pre-image: (3,1). G.CO.2 - Represent transformations in the plane, describe transformations as functions that take points in the plane as inputs and give other points as outputs. Remember : r x-axis r y-axis is a rotation by 180° about the origin. ![]() Students will be able to find compositions of isometries, including glide reflections and classify isometries.You can express all isometries as a composition of reflections.
