Step-by-step explanation:

Answer:
Theorem : Opposite sides of a parallelogram are congruent or equal.
Let us suppose a parallelogram ABCD.
Given: and (According to the definition of parallelogram)
We have to prove that: AB is congruent to CD and BC is congruent to AD.
Prove: let us take two triangles, and
In these two triangles, { By the definition of alternative interior angles}
Similarly,
And, AC=AC (common segment)
By ASA,
thus By the property of congruent triangle, we can say that corresponding sides of are also congruent.
Thus, AB is congruent to CD and BC is congruent to AD.
Step-by-step explanation:
The answer is C because you go down 1/2
Let A (1, 3, 5, 7}, B (5, 6, 7, 8}, C (5, 8} D {2, 5, 8}, and U 1, 2, 3, 4, 5, 6, 7, 8}. Determine whether the statement shown b

Answer:
True
Step-by-step explanation:
Given are some sets A, B, C, D and Universal set U.
We have

When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only
Hence here A' =
=A
This is because whenever we take any element x in A this belongs to A'
Hence 
Similarly any element y in A' also belongs to A
So A⊂A'
Together we have
Option d true
