Hello girl... By using theorem 8.1 A diagonal of a parallelogram divides it into two congrute triangles means area also will be same And AEFD is a parallelogram and AEF is a triangle and a trangle is half of parallelogram then 102/2=51 and 51 divide in to two triangle 51/2=25.5

First draw a figure in your notebook so that you can get a clear idea of the question. If ABCD is a parallelogram and we join the mid points of opposite sides then we can say that now the parallelogram is divided into two new quadrilateral which are equal. So, AEFD = BEFC Now we are given with the area of parallelogram which is 102cm square. We can say that AEFD + BECF = Area of parallelogram ABCD. Since AEFD = BECF the we can put AEFD in the place of BECF. AEFD + AEFD = 102cm 2AEFD = 102CM AEFD = 102/2 AEFD = 51cm square. HOPE THIS WAS HELPFUL

X + y is equals to w + z X+ Y + w + said is equals to 360 X + y + X + y is equals to 360 2x + 2 y is equals to 360 X + y is equals to 360 upon 2 X + y is equals to 180 Hence aob is straight

Khushbu Tripathi 3 years, 1 month ago

Given x+y = w+z To prove ; AOB is a line x+y+w+z = 360 ( reflex angle ) x+y = w+z w+z+ w+ z = 360 2w + 2z = 360 2(w+z) = 360 w+z = 360/2 = 180 Hence prove : AOB is a line
