Answer:
Step-by-step explanation:
From the given figure, it can be seen that the coordinates of the given points are:
[tex]A=(0,0)[/tex], [tex]B=(2a,0)[/tex], [tex]A=(0,2b)[/tex], [tex]P=(a,0)[/tex], [tex]Q=(a,b)[/tex], [tex]R=(0,b)[/tex].
Now, The coordinates of P, Q and R are:
[tex]P=(a,0)[/tex],
[tex]Q=(a,b)[/tex],
[tex]R=(0,b)[/tex].
Now, slope of PQ is given as:
[tex]S=\frac{b-0}{a-a}= \frac{b}{0}[/tex]
which is undefined.
Slope of RQ is given as:
[tex]S=\frac{b-b}{a-0}=0[/tex]
which are the required slope of PQ and RQ respectively.
