How does the transformation of a figure affect the size, shape and position of that figure? Translations, rotations and reflections do not change the size or shape of a figure. A dilation of a figure and the original figure are similar. Reflections, translations and rotations usually change the position of the figure.

Sketch the image of a right triangle or rectangle that has been reflected over the x- or y-axis.

Sketch the image of a dilation of a right triangle or rectangle limited to a scale factor of 1/4, 1/2, 2, 3 or 4.

The student, given a polygon in the coordinate plane, will represent transformations (reflections, dilations, rotations, and translations) by graphing in the coordinate plane.

Given a preimage in the coordinate plane, identify the coordinates of the image of a right triangle or rectangle that has been translated either vertically, horizontally, or a combination of a vertical and horizontal translation.

Given a preimage in the coordinate plane, identify the coordinates of the image of a right triangle or a rectangle that has been reflected over the 𝑥- or 𝑦-axis.

Given a preimage in the coordinate plane, identify the coordinates of the image of a right triangle or rectangle that has been translated and reflected over the 𝑥- or 𝑦-axis or reflected over the 𝑥- or 𝑦-axis and then translated.

Sketch the image of a right triangle or rectangle that has been translated vertically, horizontally, or a combination of both.

Sketch the image of a right triangle or rectangle that has been reflected over the 𝑥- or 𝑦-axis.

Sketch the image of a right triangle or rectangle that has been translated and reflected over the 𝑥- or 𝑦-axis or reflected over the 𝑥- or 𝑦-axis and then translated.
