Find height given area and base
Select one side of the triangle as your reference base and measure it.
Why: Height is always measured perpendicular to a specific base. Different bases give different heights.
If area is not known, calculate it using base-height method or Heron's formula.
Why: The area-height relationship is: Area = 0.5 × base × height. You must know area to find height.
Check that both values are valid and non-zero.
Why: Negative or zero values indicate invalid measurements. Height only exists for valid triangles.
Use: height = 2 × Area / base
Why: This is the algebraic rearrangement of the area formula. It directly gives height from known area and base.
Check that the height is positive. Verify: Area = 0.5 × base × calculated height.
Why: Back-verification catches calculation errors. Documentation preserves which base was used (important since other bases have different heights).
