Cartesian Grid - Diagram Coordinates to Area (Obtuse Triangle) - Including Negative (Level 2)

This math topic focuses on finding the area of obtuse triangles positioned within a Cartesian grid, which includes negative coordinates. It involves interpreting the diagrammatic representations of triangles with given corner coordinates and applying the formula for area calculation. This skill set helps students understand spatial relationships and geometry in a two-dimensional plane, along with enhancing their ability to work with negative values in a coordinate system.
