An isosceles triangle is a special case of a triangle where 2 sides, a and c, are equal and 2 angles, A and C, are equal. The general formula for the area of the triangle is equal to half of the product of the base and height of the triangle. C'est cette propriété et d'autres que nous utiliserons pour calculer l'aire d'un triangle isocèle. Le deuxième côté le plus court est la hauteur, L'hypoténuse, enfin, est en fait un des deux côtés identiques du triangle isocèle. The area of an isosceles triangle is the amount of region enclosed by it in a two-dimensional space.
