<p>If there is a real question here, I think it stems from your idiosyncratic usage of the words "square rectangle" and "oblong rectangle".
In more common usage, as you would no doubt find in dictionaries and geometry books, your "square rectangle" is a square 正方形, and your "oblong rectangle" is a rectangle 長方形. If you are willing to accept this common usage, there is no error in the books you are referring to. </p>

thanks monalisa. i used square rectangle and oblong rectangle here for emphasis. the book uses square for square rectangle, has no word for oblong rectangle and uses rectangle for inclusive rectangle. the word 長方形  excludes/includes squares? also 長方形 is cantonese only/mandarin only/cantonese and mandarin?

In everyday language, 長方形 does not include square; and it is true for both Cantonese and Mandarin.

AFAICT,  squares are considered as a type of rectangle in mainland China, during our whole education from primary to high schools.

Cantonese and Mandarin are both Chinese dialects. What? Are you going to ask the same question for each China dialects on this list too? https://en.wikipedia.org/wiki/List_of_varieties_of_Chinese

Could a translation error lead to squares to not be considered as rectangles? (Cantonese)
# Could a translation error lead to squares to not be considered as rectangles? (Cantonese)

(Asked by: username_0 on 2018-03-23)

I'm reading a certain set of kindergarten/lower primary maths textbooks that is written by North American authors for an Asian company.

Whenever students are asked to identify the number of rectangles in a given picture, the answer booklet gives the number of oblongs instead of the number of rectangles.

For example

> [picture with 4 circles, 2 triangles, 3 square rectangles, 2 oblong rectangles for a total of 5 rectangles]
>
> Circle \_\_\_
>
> Triangle \_\_\_
>
> Square \_\_\_
>
> Rectangle \_\_\_

The answer key would give only the numbers:

> 4

> 2

> 3

> 2

So, the last line is wrong since it should be 5.
