Mathematical Formula & Logic
Step-by-Step Worked Calculation
Scenario: Example: Triangle with sides 3, 4, 5
Classify a triangle with side lengths 3, 4, and 5.
Step 1: Check sides: 3 ≠ 4 ≠ 5, so it is scalene.
Step 2: Check angles: 3² + 4² = 9 + 16 = 25 = 5².
Step 3: Since a² + b² = c², it is a right triangle.
Step 4: Classification: Scalene Right Triangle.
Step 5: Verify: The angles are approximately 36.87°, 53.13°, and 90°.
How to Use the Classifying Triangles Calculator
- 1. Enter the three side lengths OR the three angle measures.
- 2. Click "Calculate" to classify the triangle.
- 3. Review the classification by sides (equilateral, isosceles, scalene).
- 4. Review the classification by angles (acute, right, obtuse) with verification.
