I will mark as u brainlist and will give 10 thanks.....if i will satisfy by Ur answer​

Answer 1

ANSWER-HEY MATE HERE IS YOUR ANSWER..... in a llgm there opposite sides are equal and parallel to each other and opposite angles are also equal.in abcd to prove- ab = cd and da = bc , construction- join a to c , given--ab//dc and ad//bc, proof = now ac intersect them at a and c , angle dac = angle bca (alternate angle) -1 and angle bac = angle dca (alternate angles) - 2 , now in triangle adc and cba , we have, angle dac = angle bca ( from 1) ,ac = ac (common side) , angle dca = angle bac (from 2) , so by ASA criterion of congruence we obtain, triangle ADC is congruent to triangle CBA , then ad = cb and dc = ba (cpct) proved..... hope it will helps you...... MARK ME THE BRAINLIEST......

Answer 2

Answer:

State and prove parallelogram law of vector addition.

if two vectors are considered to be the adjacent sides of a parallelogram, then the resultant of the two vectors is given by the vector that is diagonal passing through the point of contact of two vectors. ... Let the diagonal be OT
