Rectangle
Fact 1:
Everywhere around us, there are rectangular shapes more than any other shape in the world.
Fact 2:
There can be two diagonals drawn in a rectangle, but the diagonals are of different angles.
Fact 3:
Rectangles are quadrilateral, ‘quad’ meaning ‘4’ and ‘lateral’ meaning ‘sides’.
Fact 4:
For a rectangle, two parallel and opposite sides are equal in length but 4 angles are same, i.e., right angles.
Fact 5:
A rectangle is a two dimensional shape and according to some mathematicians, a three dimensional image drawing of a rectangle is
the easiest of all the mathematical shapes.
Fact 6:
Rectangles make four triangles inside but no squares even though it has four right angles constituting the shape of a rectangle.
Fact 7:
When divided diagonally, the triangles that form in a rectangle are called as the isosceles triangles.
Fact 8:
A rectangle is always flatter in shape with four distinct points.
Fact 9:
Moving a rectangle through space gives a very interesting solid structure called as the rectangular prism.

Square
Fact 1:
A square is probably one of the first mathematical shapes that you will recognise.
Fact 2:
A square has four equal side lengths.
Fact 3:
All the interior angles of a square are 90⁰ (right angles).
Fact 4:
Since all the sides and angles are the same size, a square can also be referred to as a regular quadrilateral.
Fact 5:
A square also has 4 lines of reflective symmetry; one vertical, one horizontal and two diagonal lines of symmetry.
Fact 6:
A square also has rotational symmetry. The order of rotational symmetry of a square is 4. This means it rotates onto itself 4 times in a
full turn.
Fact 7:
To calculate the perimeter of square all you need to do is multiply one of the side lengths by 4. So if you call one of the sides x then the
perimeter of the square will be 4x. For example, a square of side length 7 cm will have a perimeter of 28 cm (since 4 × 7 = 28)
Fact 8:
The area of the square can be found by squaring one of the side lengths. So if you call one of the sides x, then the area will be x². For
example, a square of side length 8cm will have an area of 64cm². There are also 10,000 cm² contained in a 1m² (since 100 × 100 =
10,000).
Fact 9:
The diagonals of a square (a line drawn from one vertex to another) meet at the centre of the shape and make four right angles at their
point of intersection.
Fact 10:
A square is one of the easiest shapes to tessellate as you can fit 4 squares around a single point (since 360⁰ ÷ 90⁰ = 4). You will find
tessellations of squares on kitchen floors, bathroom floors, patios and driveways around the world.

Circle
Fact 1:
The fraction of a circle is a degree. In each of an imaginary circle, you can find 360 degree. Each degree can define the surface of the earth.
Fact 2:
The one sided shape with an area is only owned by a circle.
Fact 3:
An infinite area is owned by a circle. It also has a straight line. You can also see some lines of symmetry.
Fact 4:
If you look at rectangle or square, it has some angles. If you look at a circle, you will find no angles. You can find some real examples of a circle
in the shape of a dimmer plate, coin and a wheel.
Fact 5:
Each circle has a diameter. It is defined with the distance across a circle through the center of the circle.
Fact 6:
If you want to know the radius of a circle, you just have to know the diameter. A diameter is twice as long as a radius. If you have a diameter in 8
inches, the radius is 4 inches.
Fact 7:
There are three parts of plane that a circle divides. The planes can be divided on the point on the circle, the points inside the circle and the points
outside the circle.
Fact 8:
Do you know the meaning of the word encyclopedia? It is circle of learning.
Fact 9:
The behavior of an animal is also defined based on the rotating circle. You can see a group of army ants. They will die because of exhaustion
when they set separated in pheromone track. The ants will keep moving in circle rotation.
Fact 10:
Human being is not equipped with an instinctive sense of direction. It makes them walk in circle and circle due to the lack of navigational clues.
When people walk in circles, they will be exhausted because of dizziness. This condition is called as geomancy.
