A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. The opposite sides of a rectangle have the same lengths and are parallel. Two sides are said to be parallel, when the distance between them remains the same at all points.
How do you identify a rectangle?
Rectangle Definition For a shape to be a rectangle, it must be a four-sided polygon with two pairs of parallel, congruent sides and four interior angles of 90° each.
What are examples of rectangles?
Examples of Rectangle Shaped Objects Laptops. If you look at a laptop, it has four sides, where the opposite sides are parallel to each other and are equal in length. Books. Cell Phones. Door. Chocolate. Table Top. Bed. Curtain.
How do you describe a rectangle to a child?
In geometry, a rectangle is a shape with four sides and four corners. The corners are all right angles. It follows that the pairs of sides opposite each other must be parallel and of the same length.
How do you know if a rectangle is a square?
So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
Are all squares rectangles?
All squares are rectangles, but not all rectangles are squares. All squares are rhombuses, but not all rhombuses are squares.
What is a rectangle in real life?
Some real-life examples of the rectangle are table tops, books, mobile phones, TV, etc.
What kind of shape is a rectangle?
A rectangle is an oblong. It has two pairs of parallel sides and four right angles. A rectangle can also be known as an equiangular quadrilateral. This is because a rectangle is a quadrilateral shape (4-sided shape) that has parallel sides, equal to one another, and all 4 corners have angles that are 90º.
Why is a rectangle special?
A rectangle is considered a special case of a parallelogram because: A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.
What properties does a rectangle have?
Here are the three properties of a rectangle: All the angles of a rectangle are 90° Opposite sides of a rectangle are equal and Parallel. Diagonals of a rectangle bisect each other.
How many faces does a rectangle have?
Rectangular Prisms It’s made up of 6 rectangular faces. When you join the sides together, it becomes a rectangular prism with 8 vertices and 12 edges.
Are all rhombuses rectangles?
A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles.
Are all rhombuses kites?
A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other and only one pair of opposite angles are equal. All sides of a rhombus are equal and opposite angles are equal. So, all kites are not rhombuses.
What is a rectangle that is not a square?
It’s called oblong. The following picture is from wikipedia. If you talk about one specific rectangular, you can just call it a rectangular. This usually implies that you do not mean a square because you did not name it a square.
Are all Quadrilaterals rectangles?
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
What’s the difference between a square and a rectangle?
Squares and rectangles are the most common shapes seen around us. The main difference between them is that a square has all equal sides, whereas, in a rectangle, the opposite sides are equal. In other words, a square is a rectangle in which the adjacent sides are equal and the interior angles are equal to 90°.
How many squares are in a rectangle?
Number of squares of side 2 units is 1 \times 2 = 2. Therefore the total number of squares in a 2 \times 3 rectangle is 6 + 2 = 8. Similarly if we consider a 3 \times 4 rectangle there are a total of 20 squares.
What objects are square shaped?
Examples of Square Shaped Objects Floor and Wall Tiles. Paper Napkins. Chess Board. Stamps. Cushions. Clock. Bread. Cheese Slice.
Can a rectangle have 4 equal sides?
A rectangle has four sides, but these are not all equal in length. The sides parallel to each other are congruent.
What is a real life example of a triangle?
Traffic signs form the most commonly found examples of the triangle in our everyday life. The signs are in equilateral triangular shape; which means that all three sides are of equal lengths and have equal angles.
Is a rectangle a regular shape?
A regular polygon must be both equilateral (all sides are the same length) and equiangular (all angles of the same measure). A rectangle is equiangular. However, a rectangle can never, by definition, be equilateral. All of its sides can never be the same length and so, it can never be regular.
How many sides are there in rectangle?
4
Are all rhombuses squares?
A rhombus is a quadrilateral (plane figure, closed shape, four sides) with four equal-length sides and opposite sides parallel to each other. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent.
Why are rectangles called rectangles?
The word rectangle comes from the Latin rectangulus, which is a combination of rectus (as an adjective, right, proper) and angulus (angle). Other geometries, such as spherical, elliptic, and hyperbolic, have so-called rectangles with opposite sides equal in length and equal angles that are not right angles.
What is the difference between rectangle and parallelogram?
The main difference between them is that a parallelogram has opposite sides equal, while in a rectangle, the opposite sides are equal with all its adjacent sides being perpendicular to each.
What are the 7 properties of a rectangle?
Rectangle Properties A rectangle is a quadrilateral. The opposite sides are parallel and equal to each other. Each interior angle is equal to 90 degrees. The sum of all the interior angles is equal to 360 degrees. The diagonals bisect each other. Both the diagonals have the same length.

A rectangular prism has six flat surfaces. In mathematics, we call a flat surface a plane. Any two-dimensional shape lies on a plane, so a.
