Question

Which statement is true for some, but not all, rectangles?

F. Opposite sides are parallel.
G. It is a parallelogram.
H. Adjacent sides are perpendicular.
J. All sides are congruent.

Answer 1

Some rectangles have adjacent sides that are perpendicular, but not all.

Step-by-step explanation:

The statement that is true for some, but not all, rectangles is option H: Adjacent sides are perpendicular. This means that while some rectangles have adjacent sides that are perpendicular, it is not a property that applies to all rectangles. Rectangles only have perpendicular adjacent sides if their angles are right angles.

For example, consider a rectangle where the length is 4 units and the width is 3 units. The adjacent sides of this rectangle are indeed perpendicular, forming right angles.

Therefore, option H is the correct choice as it adequately represents the property that applies to some, but not all, rectangles.
