This math topic focuses on calculating the area of obtuse triangles using coordinates on a Cartesian grid. The problems presented require identifying the triangle's vertex coordinates given in a diagram and using these to compute the area. There are seven questions, each with multiple choice options for answers. This subject is part of a broader learning module aimed at mastering triangle areas.
