...that the triangle must be isosceles. To construct it, we raise a perpendicular from the middle of AB, and having described from the point B as a centre,...cutting that perpendicular in C, and drawn CB and CA, we have the triangle which has the greatest surface among all those of the same perimeter, and... | |

...that the triangle must be isosceles. To construct it, we raise a perpendicular from the middle of AB, and having described from the point B as a centre, with a radius equal to half the excess of the perirrleter c over the base a, an arc cutting that perpendicular in C, and drawn CB and CA, we have... | |
