Question

The diagonal of rectangle ABCD meets at O. If angle BCD=40°, Then find angle OAD.​

Answer 1

Answer:

angle BOC=angle A O D. (vertically opposite angle)

so,

angle AOD =40

in triangle AOD,

angle OAD= angle ODA. (opp angles of Iso. Tri.)

angle A O D + angle OAD + angle ODA= 180

40+angle OAD + angle OAD=180

2(angle OAD)=140

angle OAD=70
