LEARNING INTENTIONS

●​ I can translate figures on the coordinate plane. ●​ I can use coordinate notation to describe a translation (include direction and distance). ●​ I can use precision to explain why a translated figure preserves the same size and shape of the original figure. ●​ I can reflect figures on the coordinate plane. ●​ I can use coordinate notation to describe a reflection and identify the line of reflection. ●​ I can use repeated reasoning to explain why a reflected figure preserves the size and shape of the original figure. ●​ I can rotate figures on the coordinate plane. ●​ I can use coordinate notation to describe a rotation and angle of rotation. ●​ I can use repeated reasoning to explain why a rotated figure preserves the size and shape of the original figure. ●​ I can determine a sequence of transformations that maps one figure to another figure. ●​ I can use mathematical modeling to show that two figures are congruent using a sequence of transformations. ●​ I can dilate figures on the coordinate plane. ●​ I can use coordinate notation to describe dilations on the coordinate plane and determine the scale factor used in a dilation. ●​ I can perform a sequence of rigid motions and dilations to map one figure onto another figure. ●​ I can use coordinate notation to describe the sequence of rigid motions and dilations.

●​ I can determine whether a pair of triangles is similar using Angle-Angle Similarity. ●​ I can reason and prove that two triangles are similar using angle-angle criterion. ●​ I can find an unknown length or distance using proportions or similar triangles. ●​ I can describe the relationship between the angles and sides of similar triangles.
