...to one another. In every right-angled triangle, the square of the hypothenuse is equal to the sum of the squares of the other two sides; and, in general,...the hypothenuse is equal to the sum of two similar figures described upon the two sides. In an isosceles triangle, that is, a triangle having two of its... | |
