If in a quadrilateral ABCD, AB=BC and CD=DA, then the figure is a kite.
The figure will be a kite. The very definition of kite in geometry is a quadrilateral with two disjoint pairs of adjacent sides equal.
If in a quadrilateral ABCD, AB=BC and CD=DA and AB not equal to CD, then the figure formed would be a kite.
If the measurements of a quadrilateral ABCD are given as, AB = BC = CD = DA = 4 cm. We can conclude that ABCD is a square.
If the sides of a quadrilateral ABCD touch a circle, then AB+CD=BC+AD
