Understanding of Cartesian Plane

The adjoining figure shows an isosceles triangle $OAB$ with sides $OA=AB=13$ units and $OB=10$ units. Find the coordinates of the vertices.

In the adjoining figure, $ABC$ is an equilateral triangle. Find the coordinates of the vertices.

Any point on the $x-$axis is of the form $\left(x, 0\right).$

Identify the quadrants in which each of the points $A(-1,5)$, $B(-3,-7)$, $C(3,4)$ and $D(4,-3)$ lie.

$\mathrm{I}\left(0,2\right)$ will lie on which of the axes: $\mathrm{x}-\mathrm{axis}/\mathrm{y}-\mathrm{axis}$.
