Final answer:
It is not possible to answer the question regarding triangle similarity as the options provided contain typos and do not correspond to conventional triangle notation.
Step-by-step explanation:
The question related to AQRS being a right triangle is regarding the similarity of triangles. However, the options provided (a) SAST ≈ RAST (b) ASTRATOR ≈ DASTR (c) ARST ≈ ASRTO (d) ASTRASOR ≈ ASTRARTO contain typos and don't follow the conventional naming of triangles, which are usually represented by three points. Therefore, it is not possible to determine the correct similarity statement among the provided options without further clarification. When working with right triangles, the Pythagorean theorem, which states that a² + b² = c², is often used to find the relationship between the sides of the triangle. This theorem can be rewritten to solve for the hypotenuse, c = √a² + b².
