WebFeb 2, 2024 · The first two methods use the non-parallel sides and angles of a trapezoid to determine its height. They are: h = c × sin ∠α h = d × sin ∠δ where: h - Height of the trapezoid; c - Non-parallel leg c; d - Non-parallel leg d; and sin - The sine function. The third method uses bases a and b along with the area of a trapezoid to determine its height.
