Answer:
We have to prove Δ ABO ≅ Δ CDO or, Δ DAO ≅ Δ BCO.
Step-by-step explanation:
Let us assume that ABCD is a parallelogram having diagonals AC and BD.
We have to prove that in a parallelogram the diagonals bisect each other.
Assume that the diagonals of ABCD i.e. AC and BD intersect at point O.
Therefore, to prove that the diagonals AC and BD bisect each other, we have to first prove that Δ ABO and Δ CDO are congruent or Δ DAO and Δ BCO are congruent.
In symbol, we have to prove Δ ABO ≅ Δ CDO or, Δ DAO ≅ Δ BCO. (Answer)
Answer:
A. always
Step-by-step explanation:
we know that
Parallel lines are those lines which never intersect to each other and always have same distance between them
Two lines always have same distance will only be possible when they lie on same plane
and we know that
same plane means co-planar
so, two lines will be parallel only if they are co-planar
It means that
Parallel lines are always co-planar
So,
Answer is
A. always
Remove parentheses:
