...the other two sides; in other words, BC^AB'-f-AC". Therefore, The square described on the hypolhcnuse **of a right-angled triangle, is equivalent to the sum of the squares described on the other two sides.** Cor. 1.

For example: when we prove that the square Eumpi*. described on the hypothenuse **of a right-angled triangle is equivalent to the sum of the squares described on the other two sides,** we demonstrate the fact for all right-angled triangles. But in analysis, all numbers, all lines, all... | |
