If you are given two similar rectangles, one with all measurements and the other with only one, you first need to find the conversion ratio. Let's call the rectangle that you know everything about, rectangle A, and the other rectangle B. You take the ratio of the side of rectangle B to rectangle A. You then multiply the length of rectangle A by this value, to find the length of rectangle B.
If the 'ratio' (length/width) of one rectangle is the same number as (length/width) of the other one, then the two rectangles are similar.
Every rectangle is similar in that they both have 4 sides, they both have 4 angles, and they both have 2 sides equalling one length and the other 2 sides equalling a shorter length. Every two rectangles are similar in a way but they are not all exactly the same.
Two rectangles are considered similar if their corresponding sides are in proportion, meaning the ratios of the lengths of their sides are equal. Specifically, if one rectangle has sides of length (a) and (b), and the other has sides of length (c) and (d), they are similar if ( \frac{a}{c} = \frac{b}{d} ). Additionally, both rectangles must have corresponding angles that are equal, which is inherently true for rectangles since all angles are right angles.
These are not similar rectangles so there is no obvious candidate for the ratio. Is it ratio of lengths (sides, perimeter, diameter), or ratio of area?
No not all rectangles are similar because the proportions are different.
No, not all rectangles are similar because the proportions are different.
Two rectangles are seldom but sometimes similar. They can be but they don't have to.

All squares are rectangles, as they meet the definition of having four right angles and opposite sides that are equal in length. However, not all rectangles are similar to each other; similarity requires that corresponding angles are equal and corresponding side lengths are proportional. Since rectangles can have different side lengths, they are not necessarily similar unless they have the same aspect ratio. In contrast, all squares are similar to each other because they have equal sides and angles.
Shapes that are similar to a square include rectangles and rhombuses, as they share properties such as having equal angles. Both rectangles have opposite sides that are equal in length, while rhombuses have all sides of equal length but may not have right angles. Additionally, any shape that maintains the proportionality of side lengths and angles to a square can be considered similar, such as scaled versions of the square.
There are infinitely many such rectangles.
