How do you use a protractor to determine a grid coordinate?

To determine a grid coordinate using a protractor, it is crucial to align the protractor accurately with the grid lines, ensuring you read the coordinate value correctly based on its position on the grid. The correct approach involves reading right and up, as grid systems typically set the origin point (0,0) at the bottom-left corner, with coordinates increasing in value when moving towards the right (east) and upwards (north).

Reading right ensures you are correctly identifying the horizontal coordinate, while reading up helps you establish the vertical coordinate. This method follows standard practices in navigation and mapping, where positive values increase as you move rightward and upward from the origin point of the grid. Understanding this directional approach is essential for accurately locating and interpreting grid coordinates on maps.
