Transforming On a Coordinate Plane
About these worksheets
Students practice transforming shapes on the coordinate plane. Worksheets cover reflecting shapes across the x- and y-axes, rotating shapes by 90°, 180°, and 270°, translating shapes in any direction, and calculating slope using slope-intercept form. Aligned with eighth grade geometry standards.
8g3
Reflect a shape across the x-axis or y-axis to draw its mirror image. Use the x- and y-coordinates of points to plot the reflected shape in the right place. Apply the reflection rules to change coordinates correctly, like flipping the sign of x or y. Check that the original and reflected shapes are the same size and the same distance from the axis.
8g3
Rotate a shape on a coordinate grid by 90°, 180°, or 270° in the direction given. Use the origin as the center of rotation and keep the shape’s size and orientation changes correct. Plot the new points after a rotation and connect them to redraw the rotated shape. Use rotation rules to predict how (x, y) coordinates change when turning a figure.
8g3
Practice sliding a shape left, right, up, or down on a coordinate grid without turning it. Use ordered pairs (x, y) to track how each vertex moves during a translation. Follow a translation rule or vector (like (x + 3, y - 2)) to move a figure the correct amount. Plot the translated points and connect them to draw the new image in the right place. Check that the translated shape stays the same size and orientation as the original.
8ee6
Practice rearranging a linear equation into y = mx + b form to identify the slope Isolate y by moving the x term to the other side and dividing by the coefficient of y Work with slopes that are whole numbers, negative numbers, and fractions
8g3
Dilate a figure about the origin by multiplying each coordinate by the scale factor Draw the image of a dilation on a coordinate grid Tell an enlargement from a reduction by the scale factor
8g3 8g4
Find the scale factor of a dilation from a figure and its image Tell a scale factor greater than 1 from one less than 1 Compare corresponding coordinates to find how much a figure grew or shrank
8g3
Use the rule (x, y) to (kx, ky) to dilate a point Divide by the scale factor to find a pre-image Find a scale factor from a point and its image
