As shown in the figure, in the parallelogram ABCD, ad ⊥ BD, ad = 4, do = 3 (1) find the perimeter of △ cod (2) find the parallelogram a


See the picture. It's not clear



In the parallelogram ABCD, if the area of △ cod is 6, the area of parallelogram is 0__________ .
A graph is the most common parallelogram


O is the diagonal intersection
The area of a parallelogram is____ 24______ .



The logarithm of the two diagonals of a parallelogram dividing the parallelogram into congruent triangles is ()
A. 2 pairs B. 3 pairs C. 4 pairs D. 5 pairs


There are four pairs of congruent triangles, which are △ AOD ≌ Δ cob, △ AOB ≌ Δ cod, △ abd ≌ Δ CDB, △ ACD ≌ Δ BCA. The reason is that ≌ parallelogram ABCD, ≌ OA = OC, OB = OD. In △ AOB and △ cod, OA = OC ≌ AOB = ≌ ob = odcod, ≌ AOB ≌ Δ cod, similarly ≌ AOD ≌ cob, ≌ parallel
