What is the measure of the angle formed by the coordinate axes (in $^{\circ}$)?

If $a=2, b=-3, c=-2$ and $d=-5,$ then the point $(ab, cd)$ is in the ......... quadrant.

Write whether the following statements are True or False. Justify your answer.
$(i)$ Point $(0, -2)$ lies on the $y$-axis.
$(ii)$ The perpendicular distance of the point $(4, 3)$ from the $x$-axis is $4$.

If $a=5, b=7, c=6$ and $d=10,$ then the point $(a-b, c-d)$ lies in the ......... quadrant.

Without plotting the points,indicate the quadrant in which they will lie,if:
$(i)$ ordinate is $5$ and abscissa is $-3$
$(ii)$ abscissa is $-5$ and ordinate is $-3$

If $P(-1, 1)$,$Q(3, -4)$,$R(1, -1)$,$S(-2, -3)$,and $T(-4, 4)$ are plotted on the graph paper,then the points in the fourth quadrant are:
