The image you've uploaded shows a triangle $\triangle PRQ$ with some geometric markings, including an angle at $\angle PQR$ indicated by the right angle symbol. There is also a point $M$ along line segment $PQ$, and it seems there are additional equal markings along the sides of the triangle, suggesting isosceles properties.

To find the angles of triangle $\triangle PRQ$, let's break down the information:

1. Right angle at vertex $Q$, so $\angle PQR = 90^\circ$.
2. The triangle could have properties of an isosceles triangle due to the equal markings on sides $PQ$ and $PR$, suggesting $\triangle PRQ$ might be isosceles with $\angle PRQ = \angle PQR$.

If you want exact angle measures or more details about the triangle's geometry, I can calculate them if additional numerical information is provided, or if assumptions need to be confirmed.

Would you like a detailed explanation or calculation for the triangle angles?

Here are some related questions for further exploration:

1. How does knowing a triangle is isosceles help determine its angles?
2. What can we infer if two angles of a triangle are equal?
3. What are the properties of right-angled triangles?
4. How do you find the remaining angles in a triangle if one angle is known?
5. Can this triangle be classified as a special right triangle?

Tip: In any triangle, the sum of the interior angles is always $180^\circ$. This is a key rule for solving problems related to triangle angle measures.
