** Vectors in 2D/3D Geometry**

**You will learn how to solve problems using vector methods related to the following topics ( There is also an MCQ Quiz/Test after the tutorial):**

Finding the distance between 2 lines given their vector equations.

Finding the distance of a point from a plane in 3D.

Finding the vector equation of a plane passing through two planes and a given point.

Finding out whether 2 given lines are coplanar or three given points are collinear.

Finding the vectorial equation of the line of intersection of two planes.

**You will see Vector Methods can be used to Prove Geometric Properties such as :**

The bisector of an angle in a triangle divides the (opposite) side in the ratio of the length of the 2 sides which form the angle being bisected.

Six planes through the middle of each point in a tetrahedron and perpendicular to the opposite edge, meet in a point.

A square PQRS is folded along the diagonal such that the planes of the two triangles thus formed are now perpendicular to each other. How do you find the shortest distance between PQ and RS (opposite sides, which are now in 2 different triangles ) ?

If ABCD is a tertahedron, K is the midpoint of AB and L is the midpoint of CD, prove that every line passing through K and L divides the tetrahedron into two parts of equal volume.
