Question

Which of the following can be used to describe the rectangle below

All angles are acute
Opposite sides are perpendicular
Opposite sides are parallel
All sides are the same length

Answer 1

To describe a rectangle, the following statements are applicable:

1. **Opposite sides are parallel**: This is true for a rectangle, as it has two pairs of parallel sides.

However, the other statements do not apply to a rectangle in the following ways:

- **All angles are acute**: This is false. A rectangle has four right angles (90 degrees), not acute angles (less than 90 degrees).

- **Opposite sides are perpendicular**: This is incorrect. While adjacent sides of a rectangle are perpendicular, opposite sides are not.

- **All sides are the same length**: This is false. A rectangle has opposite sides that are equal in length but not necessarily all sides the same length. That description applies to a square.

To summarize, only "Opposite sides are parallel" accurately describes a rectangle.
