Understanding the Context
Understanding the Triangle’s Geometry
With sides measuring 13 cm, 14 cm, and 15 cm, this is a scalene triangle—each side uniquely sized but perfectly balanced in proportion. Using Heron’s formula, we begin by calculating its area; this provides the foundation for finding altitudes. The formula uses the semi-perimeter: (13 + 14 + 15)/2 = 21 cm. Area then comes to approximately 84 square centimeters, a key figure confirming the triangle’s compact shape and management of edge relationships.
From this area, altitudes are derived by rearranging the formula: Altitude = (2 × Area) / Base. Because shorter bases produce longer altitudes, the shortest altitude corresponds to the longest side—here, 15 cm. This logical pivot makes the math intuitive, even for users approaching the problem for the first time.
