vidéo : Triangle Rectangle, Isocèle et Équilatéral - Les Caractéristiques Principales

This video is about the different types of triangles. A triangle is a polygon with three sides, three angles, and three vertices. The sum of the angles of a triangle is always 180 degrees. There are three main types of triangles: * **Right triangle:** A right triangle has one angle that is 90 degrees. The other two angles are acute angles. * **Isosceles triangle:** An isosceles triangle has two sides that are equal in length. The third side is called the base of the triangle. * **Equilateral triangle:** An equilateral triangle has all three sides equal in length. In this video, we will learn about the different types of triangles and their properties. We will also look at some examples of each type of triangle. We hope you enjoy the video!
