Solve Triangle Calculator

Step-by-Step Guide to Using the Solve Triangle Calculator

The Solve Triangle Calculator helps you determine missing angles and sides of a triangle by using known values. Follow these steps to efficiently use the calculator:

Step 1: Input Known Angles and Sides

Begin by identifying the known angles and side lengths of your triangle. You can enter these values into their respective fields:

• Angle A: This input is labeled “Angle A (degrees)” and requires a value between 0 and 180 degrees. Though it’s not mandatory, enter this if you know it.
• Angle B: Similarly labeled “Angle B (degrees),” input any known value between 0 and 180 degrees here.
• Angle C: For “Angle C (degrees),” enter any known value between 0 and 180 degrees.
• Side a: Under “Side a,” enter the length of side a. There’s no maximum limit, but the length should be greater than zero.
• Side b: “Side b” requires the length of side b, with similar conditions as side a.
• Side c: Enter the length of side c in the “Side c” field.

Step 2: Check the Results

After entering all known values, the calculator will compute and display the missing angles and sides based on available data:

• Missing Angle A, B, or C: If any angle is missing, the calculator will automatically compute it using the property that the sum of angles in a triangle is 180 degrees. Each calculated angle will be displayed with two decimal accuracy and suffixed with “°”.
• Missing Side a, b, or c: The calculator uses the sine rule to calculate missing sides. These values will be shown with two decimal precision.
• Perimeter: The perimeter will be calculated as the sum of the three sides (a, b, c) and presented with two decimal points.
• Area: Using the known sides and angles, the calculator finds the area and reports it with two decimal accuracy and a suffix of “square units”.

Step 3: Verify and Cross-Check

It is prudent to verify the results, especially if multiple values were calculated. Ensure the sum of the angles equals 180 degrees and that side lengths are in agreement with the cosine or sine rules where applicable.

Step 4: Utilize Calculations for Applications

With accurate measurements of angles and side lengths, you can now apply these results to real-world applications, including construction projects, academic work, and problem-solving tasks where precise triangle dimensions are needed.
