If PQ¯¯¯¯¯¯¯¯
is tangent to circle R at point Q, and PS¯¯¯¯¯¯¯
is tangent to ⊙R
at point S, what is the perimeter of quadrilateral PQRS?
A circle with radius 5 and centre point R has two points Q, and S on its circumference. One more point P is plotted on the outer surface of the circle between Q and S. Two tangents at points Q and S intersect at point P. A line joining points R and P is labelled T and its length is 4.
