### Educational Resource on Triangle Geometry

#### Topic: Self-Check Exercise - Triangle Side Lengths

**Exercise 3:**

In the given diagram, we have a triangle labeled \( \triangle MNP \) with the side lengths specified by the vertices:

- The side \( MN \) measures 5.6 units.
- The side \( MP \) measures 5.3 units.
- The side \( NP \) measures 3.4 units.

This diagram represents a scalene triangle where all three sides have different lengths.

**Understanding the Diagram:**

- **Vertex \( M \)**: This is one corner of the triangle.
- **Vertex \( N \)**: This is the next corner, connected to \( M \) by side \( MN \).
- **Vertex \( P \)**: This is the last corner, connected to \( N \) by side \( NP \) and to \( M \) by side \( MP \).

Knowing the side lengths is essential for various geometric calculations, such as:

- Determining the perimeter of the triangle.
- Applying the triangle inequality theorem to verify the triangle's validity.
- Using trigonometric identities or formulas to find angles if needed.

**Practice Question:**

_Based on the side lengths given, calculate the perimeter of \( \triangle MNP \)._

_Perimeter = MN + MP + NP_

_Perimeter = 5.6 + 5.3 + 3.4_

_Perimeter = 14.3 units_

This exercise enhances understanding of fundamental geometric principles and helps in skills like calculating perimeter and understanding triangle properties.
