Most excellent, I currently am building some custom trusses and this makes finding the cut angles easy :-), yep, I could bring out my old college text books, but this gives a visual and you can do the "what if thing". Nice application.

Ok, I get that not every iPad user is itching to know the length of the hypotenuse of a right triangle with equal sides, or the tangent to the center of the interior circle that is fits within a triangle, or the exterior circle that touches all three angles on a triangle, or any of the infinite questions you can ask about a triangle. Yes, I get that. But for the rest of us, those who either are curious or whose work deals with knowing such numbers for whatever reason, be it nuclear physics or building a doghouse, this little app is positively amazing. This is what we all wished for when taking Algebra II or Analytic Geometry. (and we only had slide rules when I did that, and weren't allowed to use them on tests) This app is amazing just to play with! If you're interested in number relationships when dealing with sines, cosines, and the like, but you don't carry around a lookup table, and you don't fancy deriving them each time in your head, then you'll LOVE this app. If you've ever used a radial saw, but didn't want to guess at the angles for a strut or truss, then you were wishing for this app. It's ridiculously simple to use. Double tap or triple tap any input scale to change the scale for faster input of large numbers. The center dial sets the fractional or decimal element of your lengths. It's all tap and drag. I can't see any reasonable problem involving triangles that can't be solved or aided with this tool. For 99 cents? C'mon! It's a no-brainer! I'd pay $99 bucks for this. Shooshie
