The formula calculates the longer side of a scalene triangle when you know the medium side and the angles opposite to the longer and medium sides. It's based on the Law of Sines, which states that the ratio of a side to the sine of its opposite angle is constant for all sides of a triangle.
The calculator uses the formula:
Where:
Explanation: This formula applies the Law of Sines to find the relationship between the sides and their opposite angles in a scalene triangle.
Details: Calculating triangle sides is fundamental in geometry, trigonometry, and various practical applications including construction, navigation, and computer graphics. Accurate side calculations help in determining triangle properties and solving geometric problems.
Tips: Enter the medium side length in meters, and both angles in radians. Ensure all values are positive and angles are within valid range (0 to π radians).
Q1: What is a scalene triangle?
A: A scalene triangle is a triangle with all three sides of different lengths and all three angles of different measures.
Q2: Why use radians instead of degrees?
A: Radians are the standard unit for angle measurement in mathematical calculations, especially when using trigonometric functions in programming and advanced mathematics.
Q3: Can this formula be used for any triangle?
A: This specific formula is designed for scalene triangles where all sides and angles are different. For other triangle types, different formulas may apply.
Q4: What if I have angles in degrees?
A: Convert degrees to radians first (radians = degrees × π/180) before using the calculator.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise based on the input values. The accuracy depends on the precision of your input measurements.
