Someone please answer this for me!!!!
A parallelogram is a quadrilateral that has two pairs of parallelsides.
In a parallelogram, oppositesides and angles are equal.
The adjacentangles add up to 180 degrees.
The rectangle is a quadrilateral that has four sides and the opposites are always parallel.
The statement "Some rectangles are not parallelograms" is false.
Option B is the correct answer.
A parallelogram is a quadrilateral that has two pairs of parallelsides.
In a parallelogram, oppositesides and angles are equal.
The adjacentangles add up to 180 degrees.
We have,
Some rectangles are notparallelograms.
The rectangle is a quadrilateral that has four sides and the opposites are always parallel.
So,
All rectangles are parallelograms.
Thus,
The rectangle is a quadrilateral that has four sides and the opposites are always parallel.
The statement "Some rectangles are not parallelograms" is false.
Option B is the correct answer.
