In both the figures, AB || CD
Fig(ii) shows a paralellogram with two adjacent sides equal and one angle 90∘.
Identify the two figures.
In Fig(i), AB || CD and in Fig(ii) shows a paralellogram with two adjacent sides equal and one angle 90∘.
In Fig. 7.139, ∠ABC=90∘ and BD⊥AC. If BD = 8 cm and AD = 4 cm, find CD.
