Let's set up an equation to find both points of intersection between a line and a circle, but do it in a way that makes it easy to tell which one (if either) lies between the terminating point and the starting point of your vector. Definition Suppose our equation of the circle is th...

做辅助线的原则(Theprincipleofdoingauxiliaryline)做辅助线的原则(The principle of doing auxiliary line)Hello.A lot of people to do the auxiliary line for many years, did not want to do what is the purpose of the auxiliary line, in fact, the auxiliary line, is to establish the relation ...
If two lines in a place have a common point then these lines are said to be intersecting line and their common point is known as Point of intersection. Example: Here m and n are two lines and they are intersecting at a point ” O”. So these lines are called intersecting lines ...
