    • @Iranger555
      @Iranger555 Рік тому +1

      K so for your kind information I tell you that-
      To prove rhombus-all sides should be equal.
      To prove square-all sides should be equal and all angles should be 90°.
      -now in rectangle all angles are always 90°. Therefore, it always becomes square when we proved all sides of rectangle equal. BTW it also becomes rhombus as every square is rhombus😉👍

      K so for your kind information I tell you that-
      To prove rhombus-all sides should be equal.
      To prove square-all sides should be equal and all angles should be 90°.
      -now in rectangle all angles are always 90°. Therefore, it always becomes square when we proved all sides of rectangle equal. BTW it also becomes rhombus as every square is rhombus😉👍
