1. Chapter 1 1.2 Create Design Ms. Robin

2. You will learn: To create a design and identify the coordinates used to make the design. Identify the coordinates of vertices of a 2-D shape.

3. Which of these designs may have been created on a coordinate grid? Flags

4. Vertex: a point where two sides of a figure meet. If plural, we say vertices. Terms:

7. Reflect on Your Findings 1.What does the flag you created look like? 1.Do you think you would have drawn the same design if you had connected the points in a different order?

8. Example 1: Identify the Coordinate of Vertices Identify the coordinates of the vertices of the shape.

9. Show You Know… Identify the coordinates of the vertices of the shape.

10. Example 2: Draw a Design Draw a flag of France on a coordinate grid. Follow the following steps: 1. Plot the vertices of your design. 2. Identify the vertices and name their coordinates. 3.Connect the vertices to make your design. 4.Color your design, if it has color. FRANCE

11. Example 2: Draw a Design Solution Draw a flag of France on a coordinate grid. Solution: 1. Plot points A to D. Connect A to B, B to C, C to D, and D to A. Color the inside of this shape blue. 2. Plot points E and F. Connect B to E, E to F, and F to C. Color the inside of this shape white. 3. Plot points H and H. Connect E to G, G to H, and H to F. Color the inside of this shape red.

12. Key Ideas: To draw a design on a Cartesian plane, Plot the vertices of your design Identify the vertices and name their coordinates Connect the vertices to make your design Color your design if it has color.
