Question

please answer this question if abcd is a rhombus and angle abd is 50 degree find bcd

Answer 1

AB = AD ( all sides of the rhombus are
equal )

=> angle ADB = angle ABD = 50 degrees
(angles opposite to equal sides are equal)

ADB + ABD + BAD = 180 degrees

=> 50 + 50 + BAD = 180
=> 100 + BAD = 180
=> angle BAD = 180-100 = 80 degrees

angle BCD = angle BAD = 80 degrees
(opposite angles of the rhombus are equal).
