Answer:
Choice C.
Step-by-step explanation:
A parallelogram is a quadrilateral with two pairs of opposite parallel sides.
There is a theorem that states that opposite sides of a parallelogram are congruent.
In this case, sides AB and CD are opposite sides.
Sides BC and AD are opposite sides.
Side CD is opposite side AB, so they are congruent.
Answer:
Choice C.
CD = AB; Opposite sides of parallelograms are congruent.
Answer:
true
Step-by-step explanation:
because CD divided AB into equal halves, so they are of course perpendicular.

Answer:
It depends.
Step-by-step explanation:
If we're able to brake the figures, then each person will get six and one sixth of a figure

But if we can't break them, then each person will get six figures with one remaining ungiven.

Add 5 to both sides
5-5+x/3=5-11
0+x/3=-6
x/3=-6
times both sides by 3
3x/3=-18
x=-18
