pie chart
graphique m à secteurs

Pie chart (pie). Pie chart or pie chart is another way to represent statistical information.

The circle is divided into sectors whose areas represent the numbers in the set.

Truck 90°

Bus 60°

Bicycle 60°

Car 150°

For example: In the information given in the figure attached to the previous entry, the angles are:

5/12 × 360° = 150° Car

2/12 × 360° = 60° Bus Bicycle
Each of them is 12

3/12 × 360° = 90° Truck

pint
demi m

Pint is a measure of volume. There are 8 pints in a gallon, and a litre is about 1.76 pints.

plan
plan m

Landscape. The landscape view of a figure is its view when viewed vertically from above.

The landscape view of a cylinder is a circle.

A map gives a landscape view of a part of the country.

plane
plan m

Plane. A plane is a flat surface.

The equation of a plane in Cartesian coordinates takes the form
. ax+by+cz=d

point
point m

Point. Points are often described by their coordinates. A point has a location but no real size.

polar coordinates
coordonnées fpl polairs

Polar coordinates. Polar coordinates are a system
of specifying the location of points by their distance r from a fixed point and by an angle 0 measured from a fixed line.

Polar coordinates take the form (0.r) versus (x,y) for Cartesian coordinates.

polygon
polygône m

Polygon. A polygon is a flat body with three or more sides.

In general, a polygon with n sides has an equal number of angles, the sum of which is (n-2) × 180. All the sides of regular polygons are equal, as are all their angles.

polyhedron
polyèdre m

Solid. A shape with each of its faces being a polygon.

There are only five regular solids: the tetrahedron, the cube, the octahedron, the dodecahedron, and the icosahedron.
