|The area of a triangle can be calculated using a formula attributed to Heron of Alexandria. This calculation requires that the lengths of all three sides be known. This activity includes an Excel file to calculate the area of a triangle, and Java and Sketchpad files to experiment with interactive triangles. Explore the Triangle Inequality Theorem while exmining the acceptable ranges for the third side of a triangle.|
