Trigonometry Master

Triangle Calculator

Looking for an easy way to calculate unknown sides or angles of a triangle? Need to quickly calculate the area or perimeter of a triangle? Whether you need to perform triangle calculations due to the nature of your work or just want to check your homework, manual calculation can be time consuming and error prone.
The good news is that now you are not alone with your calculations. Trigonometry Master saves your time and streamlines the process! Regardless of your math knowledge, with Trigonometry Master triangle calculation becomes a few second job.

Solve and draw any type of a triangle in seconds

Trigonometry Master makes triangle calculations easier than ever. The app allows you to quickly calculate sides and angles of any type of triangle. It will also calculate triangle’s perimeter and area and even draw a triangle. Isn’t it cool?
You can use the app on Mac and Windows computers as well as mobile devices with iOS and Android operating systems.

Trigonometry calculator tailored to your needs

Whatever your goal is, Trigonometry Master makes it easy to achieve the results you want with a personalized experience and a bunch of useful features. The app can be used by students, teachers, architects, engineers, carpenters, plumbers, builders, contractors, construction workers.
Customize the app by choosing the preferred input mode (2 input modes), unit of angles (degrees or radians), rounding options (up to 8 decimal places), color scheme (7 themes) and interface language (available in 20 languages).
In addition, the app keeps track of all your previous calculations and allows you to share the results via email.

How it works

While the core of many triangle calculators is the explanation of the theory behind the triangle math, the prime focus of Trigonometry Master is to provide all the necessary functionality that allows you to perform various triangle calculations in a quick and intuitive way.
With Trigonometry Master you don’t have to spend hours on memorizing formulas and crunching numbers. Just input known values and click Calculate. The app instantly shows you the results. The fields with input values have colored frames. The resulting fields are grayed out. In case you want to modify inputs, just tap/click in the field you want to update.
Based on different combinations of input parameters you can calculate missing angles and sides as well as perimeter, and area of any type of triangle. The app solves cases where you know one side and two angles (ASA and AAS), two sides and one angle (SAS and SSA), or three sides and no angles (SSS). For right triangles two parameters are sufficient – two sides or one side and one angle.
The app not only calculates unknown sides and angles but also in real-time shows how a resulted triangle looks like. Click the “Draw” button and you will instantly get your triangle drawing.

Types of triangles you can solve with Trigonometry Master

Triangles can be categorized based on the length of the sides (scalene, isosceles and equilateral triangles) and based on the measure of interior angles (acute, right, obtuse triangles). With Trigonometry Master you can solve and draw any type of a triangle by setting inputs in the form:
• 3 Sides (SSS, Side/Side/Side)
• 2 Sides and Non-Included Angle (Side/Side/Angle)
• 2 Sides and Included Angle (Side/Angle/Side)
• 2 Angles and Included Side (Angle/Side/Angle)
• 2 Angles and Non-Included Side (Angle/Angle/Side)
• 2 Sides (for Right Triangles)
• Side and Angle (for Right Triangles)
Regardless of the type of a triangle, you should enter at least one side.
