−Euclidean geometry. In coordinate geometry the standard way to define the gradient of an interval AB is rise run where rise is the change in the y‑values as you move from A to B and run is the change in the x‑values as you move from A to B. ondly, in each kind of geometry there are normal form theorems which can be used to simplify coordinate proofs. IGN – Oslandia collaboration. Vector and 3D geometry by amit m.agarwal is highly recommended by most iitjee teachers and experts. • 2x2 matrices have simple geometric interpretations – uniform scale – non-uniform scale – rotation – shear ... coordinate, resulting in a vector! steepness. For example, in a ne geometry every tri-angle is equivalent to the triangle whose vertices are A0 = (0;0), B0 = (1;0), C0 = (0;1) (see Theorem 3.13) and in Euclidean geometry … • Preview: projective transformations – what’s really going on with this last coordinate?

Coordinate Geometry Important Formulas 1) Distance Formula: d=(x 2!x 1) 2+(y 2!y 1) 2 2) Midpoint Formula: midpoint= x 2 +x 1 2, y 2 +y 1 2! −Affine transformations: translation, rotation, scaling, and shearing. Parallel Lines in a Coordinate Plane: In a coordinate plane, two non-vertical lines are parallel if and only if they have the same slope. Geometry of 2D linear trans. 3D rotations • A 3D rotation can be parameterized with three numbers • Common 3D rotation formalisms – Rotation matrix • 3x3 matrix (9 parameters), with 3 degrees of freedom – Euler angles • 3 parameters – Euler axis and angle • 4 parameters, axis vector (to scale) – Quaternions • 4 parameters (to scale) We will usually the pronumeral m for gradient.
