Triangle Calculator: Simple and Clear Math Tool

This triangle calculator helps you solve triangle problems fast. It shows you all sides, angles, area, and perimeter. You also see a diagram of the triangle.

How to Use This Tool

Follow these steps:

1. Choose the type of input you have using the dropdown menu. Options include SSS (three sides), SAS (two sides and one angle), ASA (two angles and one side), AAS (two angles and a non-included side), and SSA (two sides and a non-included angle).
2. Enter your known values in the fields that appear. For example, if you select SSS, fill in side a, side b, and side c.
3. Click the Calculate button. The tool will compute all missing values.
4. Check the results section for the triangle properties and see the diagram.

Explanation of Input Fields

The tool asks for basic measurements:

• Side a, Side b, and Side c: Enter the length of each side. Use positive numbers.
• Angle A, Angle B, and Angle C: Enter the angle in degrees. Choose numbers greater than zero and less than 180.

You only need to enter three values, one of which must be a side. This helps the tool solve the triangle.

Understanding the Output

The output has several parts:

• All side lengths with three-decimal precision
• All angles with two-decimal accuracy
• The area of the triangle in square units
• The perimeter and semi-perimeter

The diagram shows the triangle with points labeled A, B, and C. Side labels appear near each edge.

Limitations and Special Notes

The calculator checks your inputs. If values do not form a valid triangle, it shows a warning. For instance, the sum of any two sides must be greater than the third. Follow the guidelines for accurate results.

This tool uses basic math rules like the law of sines and the law of cosines. Stick to valid inputs to get proper output.

Common Use Cases

This triangle calculator is useful in many scenarios:

• Students working on geometry exercises
• Teachers seeking quick calculation examples
• Anyone needing to verify triangle measurements fast

Try it next time you work with triangles. You will find it simple and effective.
