Find the altitude of this right triangle
### Diagram of a Triangle with Height and Base Segments

The image displays a right-angled triangle \( \triangle ABC \) with the following components:

1. **Vertices and Sides:**
   - The triangle consists of vertices labeled \( A \), \( B \), and \( C \).
   - The sides opposite the vertices are as follows:
     - \( AB = c \)
     - \( AC = b \)
     - \( BC = a \)

2. **Right Angle:**
   - The triangle has a right angle (90°) at vertex \( C \).

3. **Height:**
   - The height (\( h \)) of the triangle extends from vertex \( C \) to point \( D \) on side \( AB \) such that it is perpendicular to \( AB \).
   - Height (\( h \)) intersects \( AB \) at the right angle (90°), forming the right triangle \( \triangle ACD \).

4. **Segment Lengths:**
   - Segment \( AD \) has a length of \( n = 3 \text{ cm} \).
   - Segment \( DB \) has a length of \( m = 12 \text{ cm} \).
   
The triangle is a useful illustration for discussing right-angled triangles, height in triangles, and segment lengths in geometry. It's beneficial for comprehending the relationship and properties of the geometrical elements in a right-angled triangle. 

Additionally, this diagram is useful for applying the Pythagorean Theorem, calculating areas of triangles, and understanding the concept of perpendicular height from a vertex to its opposite side. 

Key concepts to explore based on this diagram include:
- Calculating the lengths of unknown sides using the Pythagorean Theorem.
- Determining the height of the triangle.
- Finding the areas using base and height measurements.

By examining and working through examples like these, one can gain a deeper understanding of fundamental geometric principles.
