Chapter Create Design Ms. Robin

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.

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

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

Explore The Math …

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?

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

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

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

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.

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.
