Question

Two triangles on the same base or equal bases and between the same parallels are equal in area. Prove it.

Answer 1

Here is the solution for your question.

Answer 2

given: ∆ ADB and ∆ABC r triangle on the same base ...................same write theorem
Prove: ar(∆ADB)=ar(∆ ABC)

in ABFD

EF||AB or BF ||AD

both pair r opposite side r parallel

ABFD is a parallelogram

in ABCE

EFIIAB OR AEII BC

in ar(ABFD)= at(ABCE)........,
