Question

$P,Q,R$ are the vertices of an isosceles triangle. Which of the following is not the coordinates of $R$

• A. $(2,6)$
• B. $(4,4)$
• C. $(6,2)$
• D. $(8,0)$

Answer 1

The correct option is B $(4,4)$

From the graph we can see that $R(4,4)$ lies on $PQ$ itself, SO $(4,4)$ can't form a triangle $PQR$.
