TRIANGLE CALCULATOR
Solve for Area, Perimeter & Angles using 3 Sides
Introduction
Triangles are the fundamental building blocks of geometry and architecture. Whether you are calculating the area of a plot of land or solving a complex trigonometry homework, Creshy’s Triangle Calculator provides an instant solution. By simply entering the lengths of the three sides, you can unlock all the properties of that specific triangle, including its angles and classification.
Key Features
- Heron’s Formula Integration: Calculates the exact area even when the height is unknown.
- Automatic Angle Solving: Uses the Law of Cosines to determine all three internal angles in degrees.
- Triangle Classification: Tells you if your triangle is Equilateral, Isosceles, Scalene, or Right-angled.
- Perimeter & Semi-perimeter: Essential data for advanced geometry and physics problems.
Benefits
- Saves Time: Avoid tedious manual calculations involving square roots and inverse trigonometric functions.
- Accuracy in Engineering: Get precise measurements for construction or design projects.
- Educational Support: A great tool for students to verify their “SSS” (Side-Side-Side) triangle solutions.
How to Use This Tool
- Enter Side Lengths: Type in the lengths of Side A, Side B, and Side C.
- Validate Triangle: Ensure that the sum of any two sides is greater than the third side (Triangle Inequality Theorem).
- Click Solve: Hit the button to see the area, perimeter, and all three angles.
Important Terms to Know
- Equilateral: All three sides are equal.
- Isosceles: At least two sides are equal.
- Scalene: No sides are equal.
- Right Triangle: One angle is exactly 90 degrees.
FAQ
A: The tool will alert you. For a triangle to exist, Side A + Side B must be greater than Side C (and so on for all sides).
A: Yes! You can enter precise measurements like 5.5 or 10.75 for highly accurate results.
