9.1 Find the coordinates of an image (given a graph, rule of transformation, or pre-image coordinates) after a reflection across the x axis,yaxis, y = x, y = -x, y = a, or x = b. Graph the result.
9.2 Find the coordinates of an image (given a graph, rule of transformation, or pre-image coordinates) after atranslation, glide reflection, or a composition of reflections. Graph the result.
9.3 Find the coordinates of an image (given a graph, rule of transformation, or pre-image coordinates) after a rotation of 90, 180, and 270 degrees counterclockwise and counterclockwise. Graph the result.
9.4 Determine whether a figure has line, point, or rotational symmetry or neither.
9.5 Determine if a dilation is an enlargement or reduction. Find the scale factor k between two similar figures.
9.6 Find the coordinates of an image (given a graph, rule of transformation, or pre-image coordinates) after a dilation with a scale factor of k. Graph the result.
