What is "triangle pqr has vertices?

Triangle PQR has vertices at points P, Q, and R. The three vertices P, Q, and R are the corner points of the triangle and are connected by line segments to form the three sides of the triangle. The vertices determine the shape and size of the triangle. The location of the vertices also determines the type of triangle, such as equilateral, isosceles, or scalene. The vertices can be labeled in different orders as long as the corresponding sides are correctly connected. The angles and lengths of the sides of the triangle can be calculated using the coordinates or positions of the vertices.
