No, not every rectangle is a square. The definition of a square is a quadrilateral that has four right angles and its opposite sides are parallel and congruent. The definition of a square is a quadrilateral with four right angles also BUT it has four equal sides. A rectangle doesn't have four equal sides. Therefore every rectangle is not a square.

because a rectangle means that there are 4 sides and 2 sides are equal and the other two are equal. like two sides could be 6 inches and two others can be 3 inches... and a square everything has to be equal. so a square is a rectangle because it has all 4 sides equal, but a rectangle is not a square because a square needs all the sides equal.

Essential properties of a rectangle:

2. All angles are right angles.

Essential properties of a square:

2. All angles are right angles,

3. All sides are equal.

So, all squares satisfy all essential properties of a rectangle. However, not all rectangles satisfy the essential properties of a square. Hence, all squares are rectangles but not all rectangles are squares.

Hope this helps!

Rectangles are polygons with two pairs of parallel sides so that it will include squares. Square have a very strict qualification that is, all sides should be equal. So that if there is a difference in the dimensions of the sides this rectangle, it can not be considered a square.

by definition a rectangle is a four sided figure with 4 right angles. by definition a square has four equal sides and four right angles. so a square meets the definition of a rectangle but a rectangle doesnt have four equal sides. therefore a square is a rectangle but a rectangle cant be a square.

in a rectangle the 2 opposite sides have to be equal so in a square the opposite side of any side it equal so squares qualify as rectangles.

square all side must be equal but they aren't in rectangles so rectangle aren't all ways squares
