• Automatically detects the type of triangle (i.e. SSS, SAS, etc.) and displays it
• Automatically solves for the third angle when possible
• Automatically calculates the area and perimeter
• Automatically solves for the triangle when possible

Right triangles

• Automatically solves for the missing side (pythagorean theorem)
• Automatically solves for the third angle when possible
• Automatically solves for 45-45-90 and 30-60-90 triangles
• Displays all trigonometric ratios (sin, cos, tan, cot, csc, sec)
• Can display the trigonometric ratios in either plain fractions (decimals) or as simplified radicals
• Displays the simplified radical form of a decimal when a decimal is selected
• Features adjustable rounding (0-9 digits) which can be turned off
• Supports inputting inline square roots
