Yes. If the two acute angles have their measures add up to 90 degrees, and both angles share one side that is common to each angle (they are adjacent), then their non-common sides will be perpendicular.
No. This is only true of squares and rectangles. Perpendicular means that the sides meet in a right angle. A rhombus has two acute angles and two obtuse angles.
Adjacent sides are not necessarily perpendicular; it depends on the shape in question. In a rectangle or a square, adjacent sides are indeed perpendicular to each other, forming right angles. However, in other shapes like parallelograms or trapezoids, adjacent sides can be at various angles. Therefore, the perpendicularity of adjacent sides is specific to the geometric context.
They are equal.
Square & Rectangle are the only two. Rhombus (diamond) & parallelogram have adjacent sides, but no 90 degree angles (not perpendicular).
The angles sum to 90° and the angles are complementary

Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.
All angles in a square are 90o so all adjacent sides are perpendicular to one another.
A kite can have 1, 2 or 3 acute angles.
