Let's examine the image to answer the questions:

### Observations:
- The diagram shows a quadrilateral with sides labeled \(50^\circ\), \(130^\circ\), \(50^\circ\), and \(130^\circ\) at its vertices.
- A diagonal is drawn, creating two triangles within the quadrilateral.

Now, let's address each part of the questions written on the page:

1. **Number of sides**: 
   The diagram shows a **quadrilateral** with 4 sides.

2. **Name of polygon**: 
   A polygon with 4 sides is called a **quadrilateral**. Based on the equal angles, this could be a **kite** or a **rhombus**, depending on the side lengths, though no side lengths are specified.

3. **Sum of interior angles**: 
   The sum of the interior angles of a quadrilateral is given by the formula:
   \[
   \text{Sum of angles} = (n - 2) \times 180^\circ
   \]
   where \(n\) is the number of sides. For a quadrilateral:
   \[
   (4 - 2) \times 180^\circ = 2 \times 180^\circ = 360^\circ
   \]
   So, the sum of the interior angles is **360°**.

4. **Measurement of interior angles**: 
   The interior angles are labeled \(50^\circ\), \(130^\circ\), \(50^\circ\), and \(130^\circ\). Adding these together:
   \[
   50^\circ + 130^\circ + 50^\circ + 130^\circ = 360^\circ
   \]
   This confirms the sum is **360°**, which is correct for a quadrilateral.

5. **Diagonals**: 
   The diagram shows one diagonal drawn across the quadrilateral. A **quadrilateral** has **two diagonals** in total.

### Would you like further details or clarification on any part? 
Here are some relative questions to expand on the information:
1. How do we calculate the area of a quadrilateral with known angles and sides?
2. What are the properties of different types of quadrilaterals (square, rhombus, kite)?
3. Can we find the lengths of the diagonals with the given angles?
4. How do diagonals divide a quadrilateral into triangles?
5. What are the different types of angle sum theorems for polygons?

**Tip**: When solving for unknowns in quadrilaterals, knowing side lengths and diagonals can help classify the type of quadrilateral and find areas or other properties more easily.

Explore how to analyze a quadrilateral by determining the number of sides, calculating the sum of interior angles, and understanding the properties of diagonals. This problem is perfect for students in Grades 6-8 and covers essential concepts in geometry.
