### Geo Final Topics 6 and 7

#### Problem Statement:
**Find the measure of the numbered angles in the rhombus. The diagram is not to scale.**

![Diagram of a rhombus](Diagram-of-a-rhombus)

In the given diagram, the rhombus is divided into four smaller triangles. The diagram includes the following angles and sides:
- Angle at the top (marked as 44°)
- Four internal angles to be determined (labeled as 1, 2, and 3)

#### Potential Answers:
- **Option A:** \(m∠1 = 90°, \, m∠2 = 44°, \, \text{and} \, m∠3 = 46°\)
- **Option B:** \(m∠1 = 90°, \, m∠2 = 46°, \, \text{and} \, m∠3 = 44°\)
- **Option C:** \(m∠1 = 90°, \, m∠2 = 44°, \, \text{and} \, m∠3 = 44°\)
- **Option D:** \(m∠1 = 90°, \, m∠2 = 44°, \, \text{and} \, m∠3 = 68°\)

### Explanation:
To find the correct measures of the angles labeled 1, 2, and 3 in the rhombus, consider the properties of rhombuses, such as opposite angles being equal and the diagonals bisecting each other at right angles.

#### Additional Notes:
- **Diagram Specifics:** The diagram shows a rhombus with a specific angle of 44° at the top vertex, and the diagonals intersect forming four smaller triangles within the rhombus.
- **Required Knowledge:** Understanding of the properties of rhombuses and how diagonals intersect can help solve this problem correctly.

This problem is a typical example in geometry that tests understanding of angle relationships in quadrilaterals, particularly rhombuses.
