In the image, I see a geometry problem featuring a quadrilateral \(QMNP\), where:

- \(\angle QMP = 83^\circ\)
- \(\angle QNP = 41^\circ\)

The question asks to:

1. Prove that the triangles formed by the diagonals of the quadrilateral are congruent.
2. Find the size of \(\angle QNP\) (already given as 41°).

Let's focus on what the next steps could be for solving:

### 1. Proving Congruence of Triangles
To prove the triangles in question (likely \(\triangle QMN\) and \(\triangle PMN\)) are congruent, you'd need to apply one of the triangle congruence theorems, such as:

- Side-Angle-Side (SAS)
- Angle-Side-Angle (ASA)
- Side-Side-Side (SSS)

Look for any shared sides or equal angles (which may be implied based on the symmetry or properties of the quadrilateral) to establish congruence.

### 2. Finding \(\angle QMP\)
You already know two angles: \(\angle QMP = 83^\circ\) and \(\angle QNP = 41^\circ\). To find \(\angle QNP\), you would likely use angle relationships within the quadrilateral, such as:

- Sum of angles in a triangle.
- Adjacent angles if lines are parallel.

Would you like more detailed steps for these specific proofs or a breakdown of solving the angles?

---

Here are 5 questions to expand on this:

1. What properties of quadrilaterals might help in proving the triangles congruent?
2. How do you determine if two triangles share an equal angle based on given information?
3. Can the parallel postulate be applied in this geometry problem to assist with angle identification?
4. What additional information would help prove congruence through the Side-Angle-Side (SAS) rule?
5. How can the sum of the angles in a quadrilateral assist in this solution?

**Tip**: Always verify whether two triangles share a common side or angle before applying congruence theorems!

Prove that the triangles are congruent and find the size of QMP.

Solve the geometry problem of proving triangle congruence in quadrilateral QMNP using the ASA or SAS theorem. Also, calculate the missing angle QMP with provided values. Suitable for students in Grades 8-10.
