CALCULATOR
Midsegment of a Trapezoid Calculator
Find segment joining the midpoints of nonparallel sides. Example: Parallel base a: 2 m, Parallel base b: 2 m gives 2 m. a,b are lengths of parallel bases. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
a,b are lengths of parallel bases. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Trapezoid midpoint theorem: midsegment is arithmetic mean of bases.
Accepted inputs: Parallel base a: 0.001 to 1,000 m; Parallel base b: 0.001 to 1,000 m.
How the calculation works
midsegment = (a+b)/2
Worked example
With parallel base a 2 m, parallel base b 2 m, segment joining the midpoints of nonparallel sides is 2 m.
Assumptions and limits
a,b are lengths of parallel bases. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Trapezoid midpoint theorem: midsegment is arithmetic mean of bases.
