Correct Answer: Acute angled triangle

Solution : Given: That x, y, and z are the sides of a triangle. If z is the largest side and x ² + y ² > z ² ​​​​​​.
If a triangle's sides are x, y, and z, where side z is the largest side. Then,
The triangle is a right-angled triangle if x ² + y ² = z ² .
The triangle is an acute-angled triangle if x ² + y ² > z ² .
The triangle is an obtuse angled triangle if x ² + y ² < z ² .
In this case, the triangle's sides are x, y, and z, with z being the largest side.
The given condition is x ² + y ² > z ² .
The above situation satisfies the acute angle triangle criterion. So, the triangle is an acute-angled triangle.
Hence, the correct answer is an acute-angled triangle.
