1. What is an Angle Calculator?

Definition: This calculator determines the third angle of a triangle when two angles are known.

Purpose: It helps students, engineers, and construction professionals quickly find missing angles in triangular structures.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Angle \) — The calculated third angle (degrees)
• \( Angle1 \) — First known angle (degrees)
• \( Angle2 \) — Second known angle (degrees)

Explanation: The sum of angles in any triangle always equals 180°, so subtracting two known angles from 180° gives the third angle.

3. Importance of Angle Calculation

Details: Proper angle calculation is essential for structural integrity, roof framing, and geometric design in construction projects.

4. Using the Calculator

Tips: Enter two known angles (each between 1° and 179°). Their sum must be less than 180°.

5. Frequently Asked Questions (FAQ)

Q1: Why does the sum need to be less than 180°?
A: Because all three angles in a triangle must total exactly 180°.

Q2: Can I use this for right triangles?
A: Yes! If one angle is 90°, just enter it as one of the known angles.

Q3: What if I know all three angles?
A: They should sum to 180°. This calculator helps verify that relationship.

Q4: Does this work for non-triangle polygons?
A: No, this specific formula only applies to triangles.

Q5: How precise are the calculations?
A: Results are calculated to two decimal places for precision work.
