Understanding Triangle Height

What is Triangle Height?

The height (altitude) of a triangle is the perpendicular distance from a base to the opposite vertex. Every triangle has three heights, one from each base to its opposite vertex.

Formula

The height of a triangle can be calculated using the formula:

h = 2A/b

where:

  • h = height
  • A = area
  • b = base length
