Formula Used in “SSA Triangle Calculator”
The SSA Triangle Calculator employs the following formula to determine the unknown side lengths and angles of a triangle when two sides and a non-included angle are known. This scenario is often encountered in geometric problems involving **triangles**.
The standard formula used is derived from the Law of Cosines and the Law of Sines:
To find the unknown angle ( A ):
[ a = frac{b cdot sin(A)}{sin(B)} ]
To find the unknown angle ( B ):
[ b = frac{a cdot sin(B)}{sin(A)} ]
To find the third side ( c ):
[ c^2 = a^2 + b^2 – 2ab cdot cos(C) ]
Step-by-Step Breakdown of the Formula
In the formulas above, the following variables are used:
- a: length of side A
- b: length of side B
- c: length of side C
- A: angle opposite side a
- B: angle opposite side b
- C: angle opposite side c
The calculation process involves the following steps:
- Identify the known values: sides ( a ), ( b ) and angle ( A ).
- Use the Law of Sines to calculate the missing angle ( B ):
[ B = arcsinleft(frac{b cdot sin(A)}{a}right) ] - Determine angle ( C ) using the equation:
[ C = 180° – A – B ] - Lastly, calculate the unknown side ( c ) using the Law of Cosines:
- Compute ( c ) as follows:
[ c = sqrt{a^2 + b^2 – 2ab cdot cos(C)} ]
Example Calculation
Let’s illustrate this with a practical example where we know the lengths of sides ( a ) and ( b ), and the angle ( A ).
Assume:
| Variable | Value |
|---|---|
| a | 8 |
| b | 6 |
| A | 30° |
Using the formulas step-by-step:
- Calculate angle ( B ):
[ B = arcsinleft(frac{6 cdot sin(30°)}{8}right) approx 22° ] - Calculate angle ( C ):
[ C = 180° – 30° – 22° = 128° ] - Now calculate side ( c ):
[ c = sqrt{8^2 + 6^2 – 2 cdot 8 cdot 6 cdot cos(128°)} approx 10.09 ]
The final results of our calculation are:
| Variable | Value |
|---|---|
| A | 30° |
| B | 22° |
| C | 128° |
| c | 10.09 |

Understanding the Input Fields
Knowing what each input field represents and its significance is crucial for accurate calculations.
- Side a: This is one of the sides of the triangle. It is essential to have its length because it helps determine the other triangle dimensions.
- Side b: The length of the second side is important as it contributes to finding the missing angle and side in the triangle. For example, if a = 5 and b = 7, it indicates the triangle’s potential dimensions.
- Angle A: This is the angle opposite side a. It is vital for calculations; for example, if Angle A = 30°, it influences the triangle’s overall shape and size.
Examples:

Common Mistakes and How to Avoid Them
- Inaccurate Measurements: Ensure the lengths of sides and angle inputs are accurate. Double-check values if results appear strange.
- Adding Up Angles Incorrectly: Remember that the total of all three angles must sum to 180°. Verify your outputs by summing angles B and C with Angle A.
- Neglecting Side Length Comparisons: Confirm that the input values make sense geometrically—no side should be longer than the sum of the other two sides.
