Friends,
This is a Math video. This is our seventh webisode (WB-7) on "Series 8 -- Quadrilaterals".
In this video, we learn that a parallelogram has both pairs of opposite angles equal.
Then we go ahead and prove this theorem.
This video is suited for class-9 (Class-IX) or grade-9 kids.
Cheers,
Friends at Rising Pearl

Area is also equal beingg congruent triangles. There are four triangles. Opposite triaangles are equal in area. A= 1/2 a.b.Sin ♤.

Instead of saying both languages at once, why don't you add subtitles for one language?

[@sudhanshupatra3433]

at 11:08 you made a mistake
you have written angle BCD=angle BAC
it should be angle BCD=angle BAD

Sir how lhs is added with rhs??

[@dostotussigreatho]

Hi Yasmin,
Say it is given that a = b (eq.1) and also x = y (eq.2). Then we can add the two equations by simply adding the two LHS and two RHS. We can say that a + x = b + y. Hope it helps! Cheers,
