### Important Topics in NCERT Solutions for Class 12 Maths Chapter 11

The following are some of the topics covered in NCERT Solutions for Class 12 Maths Chapter 11:

• Direction cosines and Direction Ratios – How to find using different methods – when the angle is given, when a side is given, when two points are given
• Equation of Line – We form an equation of a line in different cases – one point and 1 parallel line, 2 points given. We also learn how to convert the vector form of the equation to Cartesian form
• Angle between two lines – We find Angle between two lines using Vector formula, Cartesian Formula, Using Direction Cosines and Ratios
• Shortest Distance between two lines – Finding the shortest distance between two parallel and two skew lines
• Equation of plane – Finding the equation of a plane in normal form, when perpendicular and point passing through is given, when passing through 3 Non-Collinear Points. We also find the equation of plane using intercept form, and when a plane is passing through the intersection of planes
• Coplanarity of 2 Lines – Checking if 2 lines are coplanar
• Angle between two planes – Finding angle between two planes using Vector and Cartesian method
• Distance between point and plane – Both Vector and Cartesian Formula
• Angle between Line and Plane – Vector formula only
• Equation of line under planes condition – Finding Equation of line when some condition between two planes is given.
• Point with Lines and Planes – Finding coordinates of a point when the line crosses through a plane or Finding a point where line and plane intersect.
