1. What is the Triangle Angle Sum?

Definition: The sum of interior angles in any triangle always equals 180 degrees.

Purpose: This fundamental geometric principle helps in calculating missing angles in triangular shapes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Angle 1 — First known angle (degrees)
• Angle 2 — Second known angle (degrees)
• Angle 3 — Calculated third angle (degrees)

Explanation: The sum of all three angles must equal 180°, so knowing two angles allows calculation of the third.

3. Importance of Triangle Angle Calculation

Details: Essential for geometry problems, construction planning, roof framing, and various engineering applications.

4. Using the Calculator

Tips: Enter any two angles (must be positive numbers and their sum must be less than 180°).

5. Frequently Asked Questions (FAQ)

Q1: Does this work for all triangle types?
A: Yes, the angle sum applies to equilateral, isosceles, scalene, right, acute, and obtuse triangles.

Q2: What if I only know one angle?
A: You need at least two angles (or one angle and side relationships) to determine the third angle.

Q3: Can the angles be in radians?
A: This calculator uses degrees. For radians, convert first (π radians = 180°).

Q4: What if my two angles sum to 180° or more?
A: That would violate triangle angle sum property. Check your measurements.

Q5: How accurate is this calculation?
A: Mathematically precise, assuming your input angles are correct.
