To find the values of $n$ and $m$ in the given square, we need to analyze the geometric relationships within the figure. The image shows a square with its diagonals intersecting, creating four right triangles inside the square.

Let's break down the problem:

1. Square Properties:

   • All sides are equal.
   • Each internal angle is $90^\circ$.
   • The diagonals of a square are equal and bisect each other at right angles ($90^\circ$).

2. Diagonals:

   • The diagonals of a square split the square into two equal right triangles.

3. Triangles within the Square:

   • Each of the right triangles formed by the diagonals has angles $45^\circ, 45^\circ,$ and $90^\circ$.

4. Angle Relationships:

   • The diagonals intersect at $90^\circ$ creating angles of $45^\circ$ at each vertex where they intersect the sides of the square.

Given the symmetry and the right triangle properties:

• Angles $n$ and $m$:
  • Angle $n$ is formed by the intersection of one of the diagonals with a side of the square.
  • Angle $m$ is another angle formed similarly by the intersection of the diagonals with a side of the square.

Calculations

From the properties above, let's analyze the angles within the square:

• Angle $n$:

  • This angle is formed between the diagonal and one side of the square.
  • Since the diagonals bisect each vertex angle of the square ($90^\circ$) into two $45^\circ$ angles, angle $n$ will be $45^\circ$.

• Angle $m$:

  • This angle is also formed between the diagonal and one side of the square.
  • Similarly, angle $m$ will be $45^\circ$ for the same reasons outlined above.

Thus, both angles $n$ and $m$ are $45^\circ$ each.

Conclusion

• $n = 45^\circ$
• $m = 45^\circ$
