Use this trapezoid midline calculator to quickly calculate trapezoid midline by entering the lengths of the two bases. Apply the midsegment of trapezoid formula for precise results.
a = base a
b = base b
Add both bases and divide by 2 to get the trapezoid midline.
| Base a | Base b | Midline |
|---|---|---|
| 6 | 10 | 8 |
| 8 | 12 | 10 |
| 5 | 7 | 6 |
| 15 | 5 | 10 |
| 20 | 10 | 15 |
1. Measure both base lengths.
2. Add them together.
3. Divide the sum by 2 to get the midline.
This trapezoid midline calculator automatically computes the midline using the correct trapezoid median formula with up to six decimal places.
• The midline is always parallel to the bases.
• It divides the trapezoid into two smaller trapezoids of equal area.
• Useful in construction and design.
• Simplifies calculation of area in some problems.
• Also called the median or midsegment.
