A rectangle which has its sides commensurable in power only and not in length shall be irrational and is called a medial superficies; and the line the square of which is equal to this figure is irrational and is called a medial line. Prop. XXXIV. It teaches the formation of the first bi-medial line. If two medial lines commensurable in power only and containing a rational superficies be added together the line thus formed shall be irrational and is called the first bi-medial line. Prop. XXXV. It teaches the formation of the second bi-medial line. If two medial lines commensurable in power only and containing a medial superficies be added together, the whole line is irrational and is called the second bi-medial line. Prop. XXXVI. अधिक रेखा - A greater line. If two lines be incommensurable in power, the sum of their squares be rational and twice their rectangle be a medial superficies, then the whole line formed by these two lines shall be irrational and is called a greater line.
