Question

in a rhombus ABCD,angle B=80,then angle ADB=?​

Answer 1

Since opposite angles of a rhombus are equal , if angle b is 80 degrees then angle d (or) angle ADB is :

Angle ADB = angle B ( opposite angles of a rhombus are equal )

Therefore , Angle ADB is 80 degrees

Hope this answer is satisfactory

Answer 2

Answer:

=80

Step-by-step explanation:

as in rhombus the opposite sides are congruent so

let us assume quadrilateral abcd as rhombus so ab=cd and bc= ad

therefore if b= 80 then angle adb is80 by theorem of properties of rhombus
