Question

What is a quadrilateral called, if all angles of the quadrilateral are right angles?

Answer 1

Hi , there !!

the simple definition of quadrilateral which is a polynomial which is bounded by four line segment and and sum of all angles of quadrilateral is 360°


No , you can't say that the all angle of quadrilateral are right angle because quadrilateral is figure which is formed by joining of four line segment .


it is possibility that quadrilateral should contain at right angle for example a square and rectangle.

but it is not necessary that it sure contain right angle.


so we can't say that all angle of quadrilateral are right angle.


hope it helps !!

thanks !!

Answer 2

Answer:

It may be a square or a rectangle.

Step-by-step explanation:

A quadrilateral is a four sided closed figure i.e. any figure closed by four straight lines is called a quadrilateral and it has four angles also.

Now, if a quadrilateral has all it's four angles equal to right-angle i.e. 90°, then it may be a rectangle or a square.

(i) when all the four angles are 90° and the opposite sides are equal then it is called a rectangle.

(ii) when all the four angles are 90° and also the four sides are equal then it is called a square. (Answer)
