This math topic focuses on finding missing coordinates of right triangles on a Cartesian grid, including cases with negative coordinates. Students practice calculating the area of right triangles given various coordinates and using the area to determine unknown x or y values. The problems include a range of specific area values that require applying formulas and logic to solve for the missing coordinate. This topic is a part of a broader unit on Cartesian grid geometry logic, aimed to enhance students' understanding of geometric concepts in a coordinate system.
