Answer:
True.
Step-by-step explanation:
This is true with any quadrilateral.
So, in a quadrilateral ABCD,
The pairs of opposite sides is parallel and equal.
For instance:
A = 1, 1
B = 2, 2
C = 3, 3
D = 4, 4
The midpoint of AB is (1+2)/2, (1+2)/2
The midpoint of CD is (3+4)/2, (3+4)/2
And so on and so forth, therefore the midpoints of the two opposite sides bisect the area of the rectangle.
The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
