    Required Answer:

    (1) If three angles of a quadrilateral are equal, it must be a rectangle. False

    • This case is not necessarily true because the angles can be anything other than 90° also, condition is that there sum shouldn’t exceed 360°.
    • Let these angles be 100°, then the fourth angle will be 60°. This is not a rectangle because all angles of the rectangle is equals to 90°.
    • It should have been true if all the four angles are equal in the quadrilateral. Or else, any other condition satisfying the property of rectangle is given.

    (2) If three sides of a quadrilateral are equal, it must be a parallelogram. False

    • The opposite sides of the parallelogram is equal and parallel. So, this is not true at all.
    • Three sides equal doesn’t mean that the fourth side is also equal, hence as no other condition is provided. The above statement is False.
