Finding Distance on the Coordinate Plane

​Polygons in the Coordinate Plane (Distance)

MGSE6.G.3 Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

The earth is one large coordinate plane!! Distance on the coordinate plane is used for traffic egineering, satellite imagery, astronomy, weather forcasts, gps, etc.....

​Why Learn This?

• Plot a point

• Name a point.

• determine distance by counting

• determine distance by calculating

​Success Criteria

Learning Intention: We are learning how to use coordinates to find the distance between 2 points
