# Triangle Angle-Sum Theorem Calculator Online

The Triangle Angle-Sum Theorem Calculator is a specialized tool designed to calculate the missing angle of a triangle when the other two angles are known. This simplifies the process of solving geometric problems by providing quick and accurate results. Whether you’re a student, teacher, or geometry enthusiast, this calculator can significantly reduce the time and effort required to solve triangle-related problems.

## Formula of Triangle Angle-Sum Theorem Calculator

#### Missing angle (degrees):

`missing angle = 180° - angle 1 - angle 2`

`missing angle = π - angle 1 - angle 2`

Where:

• `angle 1` and `angle 2` are the known angles in the triangle (in degrees or radians).

## Example of Triangle Angle-Sum Theorem Calculator

Let’s consider a triangle where two angles are known: 45 degrees and 60 degrees. By inputting these values into our calculator using the provided formula, we can quickly find that the missing angle is 75 degrees. This example demonstrates the simplicity and efficiency of using the Calculator for solving geometric problems.
