-- Triangle Calculator --

Angle	Opposite side
Angle A	Side a
Angle B	Side b
Angle C	Side c
Degrees Radians
Convert Deg/Min/Sec / / = Angle
This text area will display messages related to solving your triangle, once you've entered some sides and angles into the appropriate boxes above and pressed the "Solve triangle" button. You can convert between degrees and radians by clicking the radio buttons. And, you can convert an angle between degrees/minutes/seconds and a decimal fraction by entering information in the above boxes.
This triangle calculator will let you solve triangles, given a few sides and angles. It may be good enough to check trigonometry homework. But, don't use it for anything important, since this JavaScript software is complex, and we can't guarantee you'll always get accurate results.

diagram of a triangle with angles and opposite angles labelled

This diagram shows the relationship between angles A, B, and C, and the opposite sides a, b, and c, in a triangle. Your triangle may look different than this one -- this one is only an example.

If you need to convert degrees, minutes, and seconds into decimal degrees or radians, you can do that, too.
