Two geometrical objects are called similar if they both have the same shape. More precisely, one is congruent to the result of a uniform scaling (enlarging or shrinking) of the other. Corresponding ...

Similar triangles ... We know that two shapes are similar if their corresponding angles are equal, and their corresponding sides in the same proportion. The same is true for similar triangles.

Similar figures are identical in shape, but not in size. ... Remember: For any pair of similar figures corresponding sides are in the same ratio and corresponding angles are equal. ... The answer is 4.5cm. Here's how to work it out. Because the shapes are similar we can write...

If two figures are similar (the same shape), as all regular octagons are, then the ratio of any length in the figure (such as a diameter, or the perimeter) will be the same as the scale factor, and the ratio of areas will be the SQUARE of the scale factor. ... Scale Factor of Similar Shapes...

CiteSeerX - Document Details (Isaac Councill, Lee Giles): In this work we demonstrate that a recently introduced shape descriptor, the "shape context", can be used to quickly prune a search for similar shapes. Our representation for a shape is a discrete set of # points sampled from its internal and external contours.

Similar Shapes; Two figures are similar if they have the; same shape, but are not necessarily the same size. Engineers, artists, photographers, cartographers, architects, city planners, and toy manufacturers are among the many professionals who use models geometrically similar to a life-size figure.
