Answer 1

Given:-
ABCD is a parallelogram
AM and CN are perpendiculars on BD
To prove:-
AM=CN
Proof:-
first we have to prove ∆AMB=~ ∆CND

AB = CD(opp. sides of a parallelogram are equal)

angle AMB =angle CND(AM & CN are perpendiculars on BD)

angle ABM = angle CDN (alternate interior angle) (AB || CD,BD is transversal)

therefore,∆AMB =~ ∆CND (by A.A.S.)
AM=CN ( by C.P.C.T)

HENCE , PROVED!

Answer 2

include ethanol (often made from corn in the United States and sugarcane in Brazil), biodiesel (vegetable oils and liquid animal fats), green diesel (derived from algae and other plant sources) and biogas (methane derived from animal manure and other digested organic material)
