## Algebraic surfaces of the 2nd degree – Quadric surfaces

Algebraic surface of the 2nd order has class equal to 2 - it is a surface of
the 2nd degree and it is given by a 2nd degree algebraic equation \( F^2(x,y,z)=0\)
. Such surfaces are called **the quadrics**. (Wikipedia: Quadrics)

There are 5 types of quadrics:

**ELLIPSOIDS**

**HYPERBOLOIDS**

**PARABOLOIDS**

**CONES**

**CYLINDERS**
