Question

write the name of its sides and angles polygone ABCD​

Answer 1

Polygon ⬇

A polygon is a simple closed curve made up entirely of line segments. A polygon has at least 3 sides. The line segments forming a polygon are called its sides and the points at which the sides meet are called vertices.

In the example the sides of polygon ABCDE are AB, BC, CD, DE and EA. Sides AE  and ED meet at E, so E is a vertex of the polygon ABCDE. Any two sides with a common end point are called the adjacent sides of the polygon.

The pairs of adjacent sides are AB and BC; BC and CD; CD and DE; DE and EA; EA  and AB. The end points of the same side of a polygon are called the adjacent vertices. The pairs of adjacent vertices are: A and B; B and C; C and D; D and E; E and A. The joins of pairs of vertices which are not adjacent are called the diagonals  of the polygon. The diagonals are
