Answer 1

Answer:

Step-by-step explanation:

Given: ABCD is a traapezium where AB║CD.

To prove: ar(ΔAOD)=ar(ΔBOC)

Proof: As ΔABD and ΔBAC are on same base AB and between same parallels AB and CD, these Δs will have same area.

= ar(ΔABD)=ar(ΔBAC)

Now subtracting ar(ΔAOB) both sides,

=ar(ΔABD)-ar(ΔAOB)=ar(ΔBAC)-ar(ΔAOB)

=ar(ΔAOD)=ar(ΔBOC)

(Hence proved)
