In this math topic, students practice calculating areas of obtuse triangles situated on a Cartesian grid and finding missing coordinates that include negative values. The problems provide a specific area for each triangle and require the learners to determine the missing x or y coordinates from multiple-choice options. Each problem is visualized with an image, reinforcing the concept of geometric shapes on the Cartesian grid and enhancing the understanding of spatial reasoning and coordinate geometry.
