Question

.if the area of parallelogram is 45cm square,PQ=9cm and SN=6cm,find PM&QR​ 08 07 figure

Answer 1

Answer:

parallelogram pqrs is given with pq =12cm and ps =9cm.

pm is the angle bisector of angle p,that means

angle MOQ=angle MPs=x (let).

angle MOQ =angle tmr=x

(corresponding angle) .

i.e. angle son =angle PM's=x

this proves that triangle spm is isosceles triangle.

hence so = sm = 9 cm and mr = 3 cm .

angle spm = angle MTR =x

(alternate interior angle).

we got angle tmr = angle MTR = x. therefore triangle MTR is also isosceles triangle which means mr = tr = 3cm.

hence tr = 3 cm.

Hope this helps.❤️❤️❤️❤️❤️❤️❤️❤️
