Q.
In this angle OPT it is 90 degree. And OR is perpendicular drawn to OT. we need to prove triangle PRT and triangle PRO similar. Can we prove them similar through theorem 6.7 ( perpendicular drawn from vertex of right angled of right angled triangle to hypotenuse the n triangles on both the side of perpendicular are similar to whole triangle or to each other). Here angle OPT is 90 degree PR is perpendicular to OT so can we prove them from theorem
