Hw q answer
*180*
Reason adjacent angle of parallelogram is supplementry

[@geethika837]

180° mam

[@manaswigothwal5922]

The angle ABD = 40°.
Given quadrilateral ABCD , ∠DAB = 60° and ∠DBC = 80°.
Now we have to find the angle of ABD.
In triangle ABD and triangle CBD,
AD || BC (opposite angles of the parallelogram are parallel)
∠ACB = ∠CBD (Alternate angles)
∴ ∠ACB = 80°.
Now, in ΔDAB,
∠A + ∠ADB +∠ABD = 180° (Sum of all angles of a triangle)
60° + 80° + ∠ABD = 180°
∠ABD = 180° - (60° + 80°)
∠ABD = 180° - (140°) = 40°
Therefore, ∠ABD = 40°

😍😍super teaching mam

[@ghanshyamgupta7061]

Mam you are looking very pretty

[@rasmitarout1676]

Ans-180° as adjacent angles in a parallelogram are supplementary

180 degree

[@bhavanap9144]

homework :180
reason :The sum of angle DAB and angle ABC will be 180° because adjacent angle of a parallelogram are supplementry.

[@RENUKA-upsc_aspirant]

The session was amazing mam....tq soo much💕👍💝💟💞💓💘💖💗💜💛💚💙🙏...first to comment😅

[@dwijsolanki8974]

Hi

[@PS-ks3wd]

According to property of parallelogram sum of adjacent angle is supplementry so sum of the angle DAB and ABC Is 180°.
Completed

[@yuvrajtiwari3291]

Haripriya mam you are teaching very good i love your teaching skill

[@MuruGan-xy6xn]

A doubt

[@bhavanasm7106]

Reason: Anjacent angle of the parallelogram is supplementary

[@saachi1388]

Through the formula of adjacent angles I got the answer 180 degree and also if I have to add both the opposite of the diagonal 180 degree+180 degree is equals to 360 degree as we know a sum of a polygon is 360 degree

[@shivrajartzzz3237]

[@shobhanathakre1210]

Homework 👇
Adjacent angle of parallelogram are supplementry so, the answer is 180 degree

[@pritiraj1150]

[@manaswigothwal5922]

Are both the diagonals the same?
in the parallelogram ,quadrilateral ,kite ,trapezium.

[@synth423]

hiiiii

[@sudiksharamesh1097]

Sum of the angles DAB and ABC
Add up to 180 °
Because adjacent angles of a parallelogram add up to 180°

[@BRAJESHKumar-ix3px]

360 degree aprajeeta kumari

[@saachi1388]

Through the formula of adjacent angle I got answer as 180 degree

[@palvideshpande6296]

Hello Ma'am!
Ma'am can you please tell me the difference between Parallelogram and rectangle?

[@gaurangisharma495]

They are same

[@keshuandavishka5289]

180

[@sanjanaips6658]

According to property of parallelogram the adjacent angles of parallelogram are supplementary
So, angle DAC and angle ABC = 180

[@rinkisharma5806]

U didn’t take my name where I am on 2nd place

[@anshikabansal8934]

The sum of angle DAB and angle ABC will be 180° because adjacent angle of a parallelogram are supplementry.

[@jagritisingh3438]
