Question

Prove that the parallelograms on the same base (or equal bases)
and between the same parallels are equal in area.​

Answer 1

Answer:

Theorem: Parallelograms on the same base and between the same parallels are equal in area. ... BC = AD (opposite sides of a parallelogram are equal) ∠BCE ∠ B C E = ∠ADF ∠ A D F (corresponding angles) ∠BEC ∠ B E C = ∠AFD ∠ A F D (corresponding angles)
