What is "given right triangle rst?

A right triangle is a triangle with one angle measuring 90 degrees. The sides of a right triangle are called the hypotenuse, the opposite side, and the adjacent side, based on their position relative to the right angle.

In the case of the given right triangle rst, the vertices are labeled as r, s, and t, with angle r being the right angle. Each vertex corresponds to a side of the triangle, so side rt is the hypotenuse, side rs is the opposite side, and side st is the adjacent side.

To further describe the triangle, additional information such as the lengths of the sides or the measures of the angles would be needed. This information would allow for the calculation of various properties and relationships within the triangle, such as the Pythagorean theorem, trigonometric functions, and area formulas.
