Look at it alternately. 35 is seven times 5. Therefore the missing term will be seven times 8, which is 56 . The theorem of the same multiple implies that, inversely, we may divide both terms by the same number. Multiply a so that it becomes b.
Geometry is the study of figures.
Similar figures are equiangular and the sides that make the equal angles are proportional. And so on for each pair of equal angles and the sides that make them. Since H J is a fifth of J K , then L M will also be a fifth of M N . Therefore, M N will be 35 in. Next, since K H is three times longer than H J , then N L will be three times longer than L M .
