This math topic focuses on practicing the calculation of missing coordinates on a Cartesian grid to ensure the area of an acute triangle meets a specified value, which includes dealing with negative coordinates. Each problem involves a visual representation of a triangle with one or more coordinates missing, and students are tasked with calculating the missing coordinate using the given triangle area. The problems progressively include various scenarios and challenge the students to apply their knowledge of geometry and coordinate system logic.
