prove the theorem
"Two triangles having same base and equal areas lie between same parallel lines."
Hi!
Here is the proof for you.
Theorem: Triangles having the same base and equal areas lie between the same parallels.
Given: DPQR and DSQR such that ar (DPQR) = ar (DSQR).
Construction: Draw PL and SM perpendicular to QR
To prove: PS || QR
Hence, PS || QR
Cheers!
