No, not necessarily. Think of a rhombus that is not a square. Its opposite angles are equal - either both acute (sum < 180) or both obtuse (sum >180).

No. Opposite angles are equal. Adjacent angles are supplementary.
Because its base angles are equal and the 4 interior angles of any quadrilateral add up to 360 degrees so in this case opposite angles must add up to 180 degrees
A parallelogram is a four-sided figure with opposite sides of equal length and angles not equal to 90 degrees (otherwise it would be a rectangle). Diagonally opposite angles will be equal, and adjacent angles will add up to 180 degrees.

Their opposite angle are equal and all 3 angles will add up to 180 degrees
The sum of the angles of a four sided shape is equal to 360 degrees. One way to prove this is to draw a diagonal line connecting two opposite vertices, resulting in two triangles. Since the sum of the angles of a triangle equal 180 degrees, and there are two resulting triangles, then the sum of the angles of two triangles (180 + 180) will equal 360 degrees.

The line segments will have been rotated by 180 degrees.

The opposite angles add up to equal 180 Obviously the angels on the line also add up to 180 not sure of the rest. x
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
It has 2 opposite equal acute angles and 2 opposite equal obtuse angles and the 4 angles add up to 360 degrees.
Opposite angles are equal, so:One of the angles can be anything between 0 and 180 degrees (exclusive). Call this "x".The opposite angle must be the same - also "x".The other two angles must be 180 - x.
