8g3 Worksheets

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.
