Answer 1

Answer:

Triangle AOB Triangle OAD are congruent triangles

Thereforeangle OAB= Angle OAD

Angle OAB=55 deg (given)

Then Angle OAD = 55 deg

Angle BAD = 55+55 = 110 deg

Again angle OBA + angle OAB + angle BOA = 180 deg

But angle OAB = 55 angle BOA = 90 (Diagonals are perpendicular bisector)

Therefore angle OBA = 180-90-55 = 35 deg

But angle OBA= angle OBC = 35 deg

Therefore angle ABC = 35+35 =70 deg

Opposite angles in rhombus are equal

Therefore angles of rhombus ABCD are 110, 70, 110 70 (Answer
