### Educational Content on Geometry: Rhombi and Heptagons

#### Exercises:

**Geometry Problems:**

**NOPQ is a rhombus.** Given \(ON = 110\) and \(OQ = 176\). Find each measurement:

1. \(m \angle OPN =\) _______
2. \(m \angle NOQ =\) _______
3. \(m \angle NQP =\) _______
4. \(m \angle OPQ =\) _______
5. \(m \angle 1 =\) _______
6. \(m \angle 2 =\) _______
7. \(m \angle 3 =\) _______
8. \(m \angle 4 =\) _______
9. \(OP =\) _______
10. \(OR =\) _______
11. \(NP =\) _______
12. \(NR =\) _______

**Diagram Explanation:**

In the diagram of the rhombus \(NOPQ\), with \(O\) at the center, \(N\) and \(Q\) are opposite vertices. Lines and angles are marked as follows:
- \(ON\) and \(OQ\) are radii of the rhombus, measuring 110 and 176, respectively.
- The angles \( \angle OPN\), \( \angle NOQ\), etc., are marked, denoting different regions within the rhombus.
- An angle of 64° is specifically marked near \( \angle 3\).

**Additional Task:**

28. **Find the interior angle sum and exterior angle sum for a heptagon.**

**Diagram of Heptagon:**

A simple heptagon is drawn with each side representing one of its 7 edges.

### Concepts to Explore:

- **Rhombus Properties:**
  - All sides are equal.
  - Opposite angles are equal.
  - The diagonals bisect each other at right angles.

- **Heptagon Angle Sums:**
  - Interior angle sum: \((n-2) \times 180^\circ\) where \(n = 7\).
  - Exterior angle sum is always \(360^\circ\) for any polygon.

These exercises provide practice with understanding the properties of rhombi and polygons, important for strengthening geometric reasoning and problem-solving skills.
