In this post, one property of similar objects. In the previous article, we have discussed that if we want to preserve the appearance of our picture or object (that is without being stretched), we will have to enlarge or reduce it with the same proportion. That means that if we double the width of our picture, then we will also have to double the length. We have done this using the two triangles as shown below. We made sure that if we pair the sides of the two triangles, in each pair, the length of the side of the larger triangle is always twice the length of its pair. This means that the length of DF is twice the length AC, the length of DE is twice AB, and the length of EF is twice the length of BC.
