## Description

Trigonometry Pro is a clean, ad-free trigonometry toolkit for students, engineers, and anyone who works with triangles and angles every day.<br><br>Right Triangle Calculator<br>Enter any two known values — sides or angles — and the app instantly solves for all remaining sides, angles, and the hypotenuse. Supports all 9 input combinations (SSS, SAS, AAS, and more) with a live diagram that updates as you type.<br><br>General Triangle Calculator<br>Handles any triangle — no right angle required. Enter the values you know (sides, angles, or a mix) and get a complete solution across all 5 modes. The ambiguous SSA case is detected automatically and both valid triangles are shown side by side.<br><br>Interactive Theory Section<br>- Right Triangle Reference — a concise overview of sin, cos, tan, inverse functions, and the Pythagorean theorem.<br>- Pythagorean Theorem — a step-by-step animated proof built around the classic 3-4-5 triangle.<br>- Unit Circle Explorer — tap any key angle (0°, 30°, 45°, 60°, 90° …) to highlight it on the canvas and see the exact sin, cos, and tan values.<br><br>Calculation History<br>Results are saved automatically after one second of inactivity. Browse, review, or clear your history at any time from the History screen or Settings.<br><br>Settings<br>- Angle unit: Degrees or Radians<br>- Display precision: choose the number of decimal places that fits your workflow<br><br>Designed for real use<br>- Material 3 design with full dark-mode support<br>- Haptic feedback on solved results<br>- Smart keyboard navigation (Next / Done) with automatic scroll to keep input fields visible<br><br>No ads.
