Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Ideal Euclidean geometry. Use one consistent length unit. Measurements and derived quantities use floating-point arithmetic. The symmetry diagonal is split at the intersection into p and q; it bisects the perpendicular diagonal. Positive segments define a convex kite.
Example Calculation
- Symmetry diagonal, segment p: 2 units
- Symmetry diagonal, segment q: 6 units
- Other diagonal half-length: 3 units
Diagonal segments 2 and 6 and perpendicular half-diagonal 3 give area 24 and perimeter about 20.6275.
Frequently asked questions
How do I use this calculator?
Enter symmetry diagonal, segment p, symmetry diagonal, segment q, other diagonal half-length. The result updates automatically. Use Reset to restore the example values.
What method does it use?
area=(p+q)t; sides=√(p²+t²), √(q²+t²); perimeter=2(side₁+side₂).. Ideal Euclidean geometry. Use one consistent length unit. Measurements and derived quantities use floating-point arithmetic. The symmetry diagonal is split at the intersection into p and q; it bisects the perpendicular diagonal. Positive segments define a convex kite.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
