Chapter 8.6
Basics of coordinate plane (2D cartesian plane)
What You'll Learn
Identify and plot points using (x, y) coordinates on the coordinate plane
Navigate the x-axis (horizontal) and y-axis (vertical) to locate specific positions
Translate shapes by sliding them left, right, up, or down on the grid
Rotate shapes around a fixed point by turning them clockwise or counterclockwise
Reflect shapes across a mirror line to create symmetric images
Determine coordinates of transformed points after rotations, reflections, and translations
What You'll Practice
1
Plotting points given (x, y) coordinates on a coordinate grid
2
Reading and writing coordinates for points in different quadrants
3
Translating shapes by counting grid units in specified directions
4
Rotating polygons 90 degrees clockwise around a given point
5
Reflecting rectangles and polygons across vertical mirror lines
Why This Matters
Mastering the coordinate plane gives you the foundation for graphing equations, analyzing data, and solving geometry problems in higher math. You'll use these skills in algebra, trigonometry, physics, computer programming, and even everyday tasks like reading maps and following GPS directions.
