1. What is the Median on Medium Side of Scalene Triangle?

The Median on Medium Side of Scalene Triangle is a line segment joining the midpoint of the medium side to its opposite vertex. In a scalene triangle, all sides have different lengths, and this median helps in understanding the triangle's geometric properties.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_{Medium} = \frac{\sqrt{S_{Longer}^2 + S_{Shorter}^2 + 2 \times S_{Longer} \times S_{Shorter} \times \cos(\angle_{Medium})}}{2} \]

Where:

\( M_{Medium} \) — Median on Medium Side of Scalene Triangle (m)
\( S_{Longer} \) — Longer Side of Scalene Triangle (m)
\( S_{Shorter} \) — Shorter Side of Scalene Triangle (m)
\( \angle_{Medium} \) — Medium Angle of Scalene Triangle (°)

Explanation: This formula calculates the median length using the adjacent sides and the included angle, applying the cosine rule in triangle geometry.

3. Importance of Median Calculation

Details: Calculating medians in triangles is important for various geometric applications, including finding centroids, analyzing triangle properties, and solving complex geometric problems involving scalene triangles.

4. Using the Calculator

Tips: Enter the longer side and shorter side in meters, and the medium angle in degrees. All values must be valid (sides > 0, angle between 0-180°).

5. Frequently Asked Questions (FAQ)

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: How is the median different from other triangle segments?
A: A median connects a vertex to the midpoint of the opposite side, while altitudes are perpendicular to sides, and angle bisectors divide angles.

Q3: Can this formula be used for other triangle types?
A: While derived for scalene triangles, this formula works for any triangle where you know two sides and the included angle.

Q4: What units should I use for input?
A: Use consistent units (preferably meters for lengths and degrees for angles). The result will be in the same unit as the input lengths.

Q5: Why use cosine in this calculation?
A: The cosine function relates the sides and angles of a triangle through the cosine rule, which is essential for calculating medians from side lengths and angles.
