...the triangle ABG ; (vI. 1.) therefore the triangle ABC has to the triangle ABG, the duplicate ratio **of that which BC has to EF: but the triangle ABG is equal to the triangle DEF; therefore** also the triangle ABC has to the triangle DEF, the duplicate ratio of that which BC has to EF. Therefore,... | |
