**WIDTH** - Dimension perpendicular to length (horizontal plane) or height (vertical plane).

**LATITUDE **- Measured (in degrees) on a set of imaginary parallel lines drawn around the earth across the north and south poles. (see longitude)

**LITER** - Unit of capacity measurement (symbol: l).

**LINE** - A 1D geometric figure, ie one-dimensional.

**TIMELINE **- Putting events in chronological order along with the periods or dates of the occurrence of the facts.

**LOGARITHM - **Logarithm of **N** at base a (log_{The} N) is a number **x** such that^{x} = N. Base can be any number although the most used are base 10 (decimal logarithm) or base **and** (neperian logarithm).* Rules*: log_{B}(x * y) = log_{B}(x) + log_{B}(y); log_{B}(x / y) = log_{B}(x) - log_{B}(y); log_{B}(x^{ no}) = n log_{B}(x)

**LONGITUDE** - Measured (in degrees) in a series of imaginary lines (meridians) centered on the north pole or south pole (perpendicular to the earth axis) on the earth's surface.

**LOSANGO -** A parallelogram with four equal sides, two to two parallel, and the opposite angles obtained from the same diagonal are equal.

**GEOMETRIC PLACE - **A set of points that meet a condition. For example, the set of equidistant points of a given line will be two lines parallel to the first at this distance. Another example: the 4 cm equidistant points of a fixed point P is a circumference with center in P and radius 4.
