GEOMETRY TRANSFORMATION objective: Students will be able to Students will be able to identify and compare the three congruence transformations, apply the three congruence transformations to coordinates of the vertices of figures, identify and apply dilations, and apply transformations to real-world situations. - represent /draw and interpret the results of transformations and successive transformations on figures in the coordinate plane. ? translations ? reflections ? rotations (90°, 180°, clockwise and counterclockwise about the origin) ? dilations (scale factor) - identify locations, apply transformations, and describe relationships using coordinate geometry. Compare transformations that preserve distance and angles to those that do not. Solve problems involving transformations in order to solve real-world problem. Ability to make connections between function?? transformations (F.BF.3) and geometric transformations ? Knowledge that rigid??transformations preserve the shape of a figure Ability to use appropriate vocabulary to describe the rotations and reflections ? Ability to use the characteristics of a figure to determine and then describe what happens to the figure as it is rotated (such as axis of symmetry, congruent angles or sides…. Ability to interpret and perform a given sequence of transformations and draw the result ? Ability to accurately use geometric vocabulary to describe the sequence of transformations that will carry a given figure onto another STANDARDS Using transformational geometry, create a reflection, translation, rotation, glide reflection and dilation of a figure; and apply transformations and use symmetry to analyze mathematical situations ? Experiment with transformations in the plane Cluster Note: Build on student experience with rigid motions from earlier grades. Point out the basis of rigid motions in geometric concepts, e.g., translations move points a specified distance along a line parallel to a specified line; rotations mo
