Are rectangles always similar to each other?

Similar shapes need to have the same number of sides, the same angles and the ratio of the sides needs to be the same. Rectangles are not always similar to each other because they can have different dimensions, which would break the "same ratio" rule.


Does similar polygons always have the same area?

no. similar polygons do not have the same area. similar just means that they have the same angle measurements and are proportional.


Is there an example of 2 rectangles with the same area but different areas?

No. Many investigators have searched for such an example, but none have found it yet. According to all published research so far, two rectangles with the same area always have the same area. But the search goes on, in many great universities.


Why does rectangles have the same area and perimeter?

they dont


If two rectangles are similar then the corresponding sides are?

If two rectangles are similar, they have corresponding sides and corresponding angles. Corresponding sides must have the same ratio.


Are two rectangles always the same?

they can be any size but have to be the same shape


Are some rectangles simialar?

YES!!! 'Similar' in mathematics means that the sides and area are in given proportions. 'Congruent' in mathematics means that two shapes have the same length of sides and the same area, AND the same angular values.


How many rectangles have the same area and perimeter of 18?

thare is only 1 differint rectangles


Do two different rectangles with the same perimeter necessarily have the same area?

no


If two rectangles have the same area do they also have to have the same perimeter?

Not necessarily. Let's say that there is a circle with the area of 10. Now there is a star with the area of 10. They do not have the same perimeter, do they? That still applies with rectangles. There might be a very long skinny rectangle and a square next to each other with the same area, but that does not mean that they have the same perimeter. Now if the rectangles are congruent then yes.


How can 2 rectangles have the same area?

1x36 and 2x18 is an example


How can you use ratios of adjacent sides to prove if two rectangles are similar?

You can use ratios of adjacent sides to prove if two rectangles are similar by comparing to see if the ratios are the same
