Do you need to learn how to determine the angles and lengths of a Right Angle Triangle? Need to clearly understand which of the sine, cosine and tangent ratios to use? Need to know how to determine the angle when you know two of the sides. If the answer is Yes to any of these questions then this App is for you. The Angles Calculator not only calculates the answers for you but it also tells you how it did it so you can understand how and when to apply the rules for right angle triangles. New this version: Now the area of the triangle is calculated for you. An explanation of how this was done is also given. The App is simple to use. Just enter an angle and a side or two sides and all the others will be calculated for you. To see how the answers were arrived at just select the 'Workings' button and a page is shown with a comprehensive set of steps to show how each was calculated. To enter a value for an angle or a side just touch the diagram on or near the one you want to specify. The keypad pops up. Enter the value you want and select OK. Select the other value and do the same. When you press OK this time the App calculates the other values. To start over select 'Clear All'. All values are reset. You can now specify two other values. Note: The App cannot calculate the answers if you specify two angles and no sides. It is mathematically impossible. You have to specify an angle and a side or two sides.

If yoour employer or principal contractor has asked you to use Tribuco, here's what it actually is. Quality on site doesn't slip because people don't know what to do. It slips because the right behaviours aren't consistently shown, across projects, teams and supply chains. Every accreditation, every training course, every compliance tick box covers skills, knowledge and experience. None of it covers behaviour, the part that actually shapes what happens on site day to day. Under the Building Safety Act, businesses are required to demonstrate competence, and that now includes behaviour, not just skills, qualifications and experience. Principal contractors and businesses across the supply chain need to show this is being done consistently, not just recorded once and forgotten. 1. Guidance is delivered in short, practical formats, built for how people actually take in information on site, not buried in another document nobody reads. 2. Tribuco does not track or monitor individuals. It's built to support consistent behaviour across a project, not to record or watch anyone personally. 3. Tribuco is how your project is meeting that requirement. It's understanding, not surveillance
