Yogita Ingle 6 years, 1 month ago

ABCD is rhombus
AB = AD
also diagonals bisect each other
DO = OB
AO is common
so
Triangle AOD congruent to triangle AOB
so angle AOD = angle AOB.....c.p.c.t.
but angle AOD + angle AOB = 180......linear pair
so angle AOD = angle AOB = 90

A quadrilateral is a closed plane figure with four sides(edges) and four vertices(corners).
The sum of the interior angles of a quadrilateral is 360o.
A quadrilateral whose both pairs of opposite sides are parallel is called a parallelogram.
A quadrilateral that only has one pair of opposite sides that are parallel is called a trapezium.
A quadrilateral with all sides equal is called a rhombus.
