Triangles: Area, Base, and Height

The video tutorial covers how to calculate the area of triangles using different base-height pairs. It explains the use of index cards to find heights in rotated triangles and demonstrates drawing heights for various bases. The tutorial also addresses calculating areas for triangles not aligned with grid lines and concludes with a summary and homework instructions.
