ts will just make up the square on the hypothenuse. at B. Let ABC be a right angled triangle Upon A C describe the square AGED, right angled at B. Upon A C describe the and upon A B and BC describe the squares A B G F, and B C I H, and pro- square AEDC; from the points DE, draw D F, and E G,… … Now, in the triangles A B C, D I C, the angles B and I, being right angles, are equal; and because each of the angles B C I, AC D, is a right angle, take away the angle A C I, which is common to both, Because the angle C A K, adjacent to and the remaining angles ACB, I CD, C A D, is a right angle,…
