Three Dimensional Geometry | Class 12 Maths || NCERT Chapter 11 || 10 Board Exam Questions

Three Dimensional Geometry | Class 12 Maths || NCERT Chapter 11 || 10 Board Exam Questions Three-Dimensional Geometry (3D Geometry) Class 12 – also known as three dimensional geometry class 12 or solid geometry – is Chapter 11 in NCERT Maths book. This chapter extends 2D lines and planes into real 3D space with X, Y, Z axes, helping us find directions, equations, angles, and distances in everyday 3D world. Key concepts include direction cosines and direction ratios (with formula l² + m² + n² = 1), equation of a line in space (symmetric, vector, Cartesian forms like (x-x₁)/a = (y-y₁)/b = (z-z₁)/c), equation of a plane (ax + by + cz + d = 0 or normal form), angle between lines, angle between planes, angle between line and plane, distance from point to line, distance from point to plane, shortest distance between two skew lines (using cross product formula |(P₂ - P₁) · (d₁ × d₂)| / |d₁ × d₂|), foot of perpendicular, image/reflection of point, and more. It links strongly with vector algebra class 12 (dot/cross products help a lot). For quick learning, watch 3d geometry class 12 one shot videos perfect for revision, boards, or JEE. Popular ones include 3d geometry class 12 one shot jee, 3d geometry class 12 one shot pw, 3d geometry class 12 one shot arvind kalia, 3d geometry class 12 one shot sachin sir, 3d geometry class 12 one shot dear sir, 3d geometry class 12 one shot jee mains, 3d geometry class 12 one shot ashish sir, 3d geometry class 12 one shot boards, 3d geometry class 12 one shot revision, 3d geometry class 12 one shot bihar board, 3d geometry class 12 one shot ncert, 3d geometry class 12 one shot nexa classes, 3d geometry class 12 one shot cbse, and 3d geometry class 12 one shot jee most important questions. Great teachers: Ushank Sir (Science and Fun, super for NCERT + CBSE/Bihar Board), Arvind Kalia Sir (JEE Nexus/Unacademy, best for JEE Main & Advanced with PYQs and tricky skew lines/shortest distance), NEXA Classes, Ignited Minds, Shivang Maths Academy, etc. Many are in Hindi/English, some with introductions or full in Kannada/Tamil. Practice is key!
