Answer 1

Step-by-step explanation:

insufficient data if the non parallel sides r eq then it is possible to solve

Answer 2

Answer:

In the given figure, ∆ABC and ∆ABD lie in between the same parallel lines AB and CD and have the common base AB.

As per theorem, triangles which lie in between the same parallels and has the same common base have equal areas.

Therefore, the triangles ∆ABC and ∆ABD have the same areas.

Which implies that,

ar(∆ABC) = ar(∆ABD)

Therefore, the correct answers to the question are,

a) ar(∆ABC) = 20 cm^2

b) ∆ABC & ∆ABD and ∆ACD & ∆BCD are the two pairs of triangles of equal areas.
