This math topic focuses on calculating the area of obtuse triangles, designed for learners in the introductory-level unit on triangle areas. It includes seven questions where students are presented with images of obtuse triangles and are tasked with selecting the correct area from multiple choices. Each question offers six possible answers, expressed in squared units that vary from inches to miles. This topic aims to enhance students’ understanding of geometry by applying area calculation formulas to obtuse triangles, fostering both problem-solving and analytical skills in a visual and interactive format.
