http://ItsMyAcademy.com/Straight-Line-Mathematics/ For Complete List of Videos To find angle between the two lines if slope of the both lines are given then, we have to use the formula that we have discussed in above video lesson of Straight Line mathematics. There is a very simple concept behind the angle between two straight lines. There two possible cases whenever two straight lines intersect each other. There is formation of angles and 2 types of angles- one pair of acute angle and other one pair of obtuse angle. We can find both types of the angle between two lines using that formula.
I hope this straight line video lesson was helpful in gaining some concepts of straight line mathematics.
