Use coordinates to compute perimeters of polygons and areas of
triangles and rectangles, e.g., using the distance formula.
Geometry - Fluency Recommendations
Fluency with the use of coordinates to establish geometric results, calculate length and angle, and use geometric representations as a modeling tool are some of the most valuable tools in mathematics and related fields.
