How The lengths of the sides of a triangle are 13, 14, and 15 units. Find the length of the shortest altitude. A Clear, Neutral Breakdown
To determine the shortest altitude, start with the area calculation, since altitude length depends on base and area. For a triangle with sides a = 13, b = 14, c = 15:
First, compute the semi-perimeter:
s = (13 + 14 + 15) / 2 = 21

Next, apply Heron’s formula:
Area = √[s(s−a)(s−b)(s−c)] = √[21×(21−13)×(21−14)×(21−15)] = √[21×8×7×6]
= √[7056] = 84 square units.
With area known, the altitude corresponding to any side is:
Altitude = (2 × Area) / base.
Thus:
Altitude on side 13 = (2×84)/13 ≈ 12.92
Altitude on side 14 = (2×84)/14 = 12
Altitude on side 15 = (2×84)/15 ≈ 11.2.
The shortest altitude—facing the largest base—is 11.2 units, lying on the 15-unit side.
This precise calculation underscores how mathematical consistency applies across contexts—from mobile learning tools to engineering design—reinforcing accurate problem-solving rooted in reliable formulas.

Things People Often Misunderstand About The lengths of the sides of a triangle are 13, 14, and 15 units. Find the shortest altitude
A common misconception is that altitude length depends solely on the longest side, overlooking how area unifies all sides. Another is confusing integer side triangles with perfect symmetry—while 13-14-15 forms a near-equilateral balance, its altitudes vary precisely due to differing base lengths. Additionally, some confuse generic triangle formulas with specific case adaptations. To avoid confusion, always verify the triangle inequality holds and consult reliable geometry sources. Educating users on these nuances builds trust and deepens engagement.
