ABCD is a square with sides measuring 4 cm.
Is ABCD a rectangle?
We know that the figure shows a square and that, in a square, every pair of opposite sides are parallel.
We also know that every pair of opposite sides in a rectangle are parallel as well.
Therefore, the quadrilateral ABCD is indeed a rectangle.
Yes
It is possible to draw a quadrilateral that is not a rectangle, with the sum of its two adjacent angles equaling 180?
Think of it like this: a square is a special rectangle where all four sides happen to be equal! Just like how a motorcycle is still a vehicle, even though it's different from a car.
A rectangle needs two things: opposite sides must be parallel, and all four angles must be 90°. Since squares have both of these properties, they qualify as rectangles!
Yes! Any four-sided shape with parallel opposite sides and four right angles is a rectangle. This includes squares, but also shapes where length ≠ width.
Understanding that squares are rectangles helps you use rectangle formulas for squares too! Like area = length × width works for both shapes.
That's the opposite question! Not all rectangles are squares - only rectangles where all four sides are equal can be called squares.
