In which ratio does the $X$-axis divide the line segment joining $A(1, 2)$ and $B(4, -5)$ starting from $A$?

Find the coordinates of the point $Q$ on the $x$-axis which lies on the perpendicular bisector of the line segment joining the points $A(-5, -2)$ and $B(4, -2)$. Name the type of triangle formed by the points $Q, A$ and $B$.

The segment joining $A (-2, 1)$ and $B (7, 8)$ is divided into five congruent segments. Find the coordinates of the third point from $A$.

The distance of point $P(2, -3)$ from the $X$-axis is $\ldots \ldots \ldots \ldots .$.

The end points of the diameter of a circle are $(2, 4)$ and $(2, 6)$. The radius of the circle is:

Students of a school are standing in rows and columns in their playground for a drill practice. $A, B, C$ and $D$ are the positions of four students as shown in the figure. Is it possible to place Jaspal in the drill in such a way that he is equidistant from each of the four students $A, B, C$ and $D$? If so,what should be his position?
