ASA Triangle Calculator
Result
ASA Triangle Calculator Solve a triangle from the angle-side-angle (ASA) case: two angles and the side between them. Enter angle A, angle B, and the included side c, and the calculator finds the third angle, the remaining two sides (using the law of sines — free online calculator.
Formula
- ASA Triangle Calculator calculates its result from Angle A (deg), Angle B (deg), Side c. It uses the formula Calculated with the verified ST Calculator runtime.. Change any input to recalculate the result instantly.
- The main inputs are Angle A, Angle B, Side c. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: ASA Triangle
- Angle A: 50 deg
- Angle B: 60 deg
- Side c: 10
Using Angle A (deg) = 50, Angle B (deg) = 60, Side c = 10, the calculated result is C deg: 70 | a: 8.152074691 | b: 9.2160498511 | Area: 35.2995188796.

Frequently asked questions
What does the ASA Triangle calculate?
ASA Triangle Calculator Solve a triangle from the angle-side-angle (ASA) case: two angles and the side between them. Enter angle A, angle B, and the included side c, and the calculator finds the third angle, the remaining two sides (using the law of sines — free online calculator.
Which values should I enter?
Enter Angle A, Angle B, Side c using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: Method: Compute C = 180° − A − B, then use the sine rule a = c·sin(A)/sin(C) and b = c·sin(B)/sin(C); Area = ½ab·sin(C)..
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
