This math topic focuses on calculating the area of acute triangles plotted on a Cartesian grid. The problems involve using given coordinates, including negative values, to determine the area of each triangle. Each question provides a diagram of the triangle along with its vertex coordinates, and multiple choice answers are given for students to select the correct area. This topic forms part of a broader unit on triangle area calculations.
