Here you are given the distance formula to find the distance between two points ,section formula
to find the coordinate of a point which divides a line segment in a particular ratio, the formula to
find the midpoint, and the formula to find the slope of a line.
Here you will find some of the standard equations of straight line like point - slope form,
two point form, intercept form etc, and the condition for two lines to be parallel, and the
condition for two lines to be perpendicular.
The general equation of a circle, the equation of a circle given the centre and radius, equation of a circle
for which the endpoints of the diameter are known, equation of the tangent to a circle , condition for two
circles to cut orthogonally are given .
