| \( A_{area} \) = area | \( in^2 \) | \( mm^2 \) |
| \( h \) = height | \( in \) | \( mm \) |
| \( c \) = major axis | \( in \) | \( mm \) |
| \( d \) = minor axis | \( in \) | \( mm \) |
- Ellipse segment (a two-dimensional figure) is an interior part of an ellipse bound by a chord and an ellipse.
- Chord is a line segment on the interior of the ellipse.
- Major axis is always the longest axis in an ellipse.
- Minor axis is always the shortest axis in an ellipse.
- Semi-major axis is half of the longest axis of an ellipse.
- Semi-minor axis is half of the shortest axis of an ellipse.
