How to Use the Angle Calculator Tool

Using the Angle Calculator is straightforward. Here’s a step-by-step guide:

  1. Enter Angle A: Type the value of the first angle in degrees (between 0° and 180°) in the "Angle A" field.
  2. Enter Angle B: Type the value of the second angle in degrees (between 0° and 180°) in the "Angle B" field.
  3. Click Calculate: Press the "Calculate" button to find the unknown angle (Angle C) and the sum of all angles.
  4. View Results: The tool displays Angle C and the total sum of angles, allowing you to verify accuracy.
  5. Reset: To clear the inputs and start a new calculation, click the "Reset" button.

Example of Angle Calculation

Suppose you know two angles of a triangle:

  • Angle A = 50°
  • Angle B = 60°

Step 1: Enter Values

Input 50 in Angle A and 60 in Angle B.

Step 2: Calculate

Click "Calculate."

Step 3: View Results

The tool will show:

  • Angle C = 70°
  • Sum of angles = 180°

This confirms the triangle's angles add up correctly, making it reliable for any geometric calculation.
