To quickly assess the difficulty of the text, read a short excerpt:


For the diagonals A C, B D bisect each other (Prop. XXXIV. Bk. I.) ; hence, in the trian- gle ABC, XB^ + BO^ = 2 AE^ + 2 BE® (Prop.
XIV.) ; also, in the triangle A D C, ad' + DC' = 2 A E® + 2 D E^ 94 ELEMENTS OP GEOMETRY.
Hence, by adding the corresponding sides together, and observing that, since B E and D E are equal, B E and D E^ must also be equal, we shall have, AB' + BC'' + ad' + DC' = 4 AB' + 4 D"e'.
But 4 AE' is the square of 2 A E, or of A C, and 4 DE' is the square of 2 D E, or of B D
... (Prop. VIII. Cor.) ; hence, BA' + BC' + CD' + ad' = A^' + BD'.
Pkoposition XVI. — Theoeem.
249. In any quadrilateral the sum of the squares of the sides is equivalent to the sum of the squares of the diag- onals, plus four times the square of the straight line that joins the middle points of the diagonals.
Let A B C D be any quadrilateral, the C diagonals of -whicli are AC, D B, and E P a straight line joining their mid- dle points, E, P ; then the sum of the squares of A B, B C, C D, A D is equiv- alent to AC' -f BD' + 4 EF', a Join E B and E D ; then in the triangle ABC, AB' -j- BC' = 2 AE' -f 2 BE^ (Prop.
