Solve triangles by entering two sides and one angle, two angles and one side or three sides to find remaining values as used in trigonometry.

Angles are available in degrees, radians, grads or degrees with minutes and seconds.

The ▲² button shows second solution if one exists (ambiguous case).

Simple to use, accurate, and easy to configure. Works great for construction, site surveying, etc. Just choose between right triangle or isosceles triangle, then fill in the known values, hit the calculate button and the results are given. To set the calculator outputs, hit the three dots at the top of the screen. Precision: how many digits output (0, 1, 2, 3, 4, or 5). Angle Units: (decimal degrees, rad, grad, deg-min-sec).

Hi All. I needed to work out metal sizes for some adjustable solar panel brackets. This app made it easy, thanks. I would like the result to display the formula "for an added feature" if that would be possible, to help my old brain cells remember how I used to do calculations like this. 👍😃

UI is nice, but for a paid product, this thing rounds off to two digits after the decimal, which is not an acceptable rounding error for me. If I input 3-4 digits after a decimal, I need the answer to not be rounded off to two places, since I'm working with engineering prints and need a precise triangle solving app in the field.

Super handy as I dont always have my scientific calculator on me really adjustable ie reads out to 5 decimals I believe or less if I adjust the settings which is great. No ads which I am very happy about

Actuate easy tool. Not sure What the decimal point complaints are, go to settings and change them from nil to up to 5. I have the paid version has extra features use it all the time when tuning my race car

Very useful. Awesome that I can rotate the triangle, I only wish I could mirror the triangle for reference.

Pretty pretty please include a dark/black theme. Pretty spiffy. I'm using it for woodworking.

True it once. Didn't like it. Can't get a refund. Against policy?

Better than my electronic calculator. TKS
