Circle



Circle:

Image result for circle images
  • A Circle is a closed  figure in a plane and it is the collection of all those points in the plane,which are at a constant distance from a fixed point in the plane.
  • The  fixed point is called the centre of the circle and the constant distance is called the radius of the circle.        
  • There is one and only one circle passing through three given  points.

Angle subtended by an arc of a circle

  • The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remianing part of the circle.
  • The angle subtended in a semicircle is aright angle.
  • Angles in the same segment of a circle are equal.

Addition is fun!

Image
Addition is ... ... bringing two or more numbers (or things) together to make a new total. Here 1 ball is added to 1 ball to make 2 balls:   Using Numerals it is:      1 + 1 = 2       And in words it is:   "One plus one equals two" Example: When we add  2  and  3  we get  5 . We can write it like this: 2 + 3 = 5 Swapping the position of the numbers we are adding still gets the same result! 3 + 2 = 5 ... also ...   2 + 3 = 5 More Examples: 5 + 1 =  1 + 5  = 6 7 + 11 =  11 + 7  = 18 4 + 100 =  100 + 4  = 104 Larger Numbers: Use Addition in Columns To add larger numbers use  Column Addition  :   Names Other names for Addition are  Sum, Plus, Increase, Total And the numbers to be added together are called the " Addends ": For better understanding: https://www.khanacademy.org/math/early-math/cc-early-math-add-sub-basics/cc-early-math-add-sub-intro/v/addition-introduction https://www.khanacademy.org/math/arithm

Learn the four basic operations of mathematics

Image
                        Four basic operations of  Mathematics Addition Subtraction Multiplication Division Addition   is a mathematical operation that explains the total amount of objects when they are put together in a collection. Subtraction   is the arithmetic operation that is the opposite of addition. Subtraction is used when you want to know how many objects are left in the group after you take away a certain amount of objects from that group.

Introduction to area

Image
Area               In maths, geometry is the science of finding the measurements of shapes. There are several different measurements that can be calculated depending on the type of shape. These measurements are called dimensions. Width, depth, or height are examples of dimensions. Shapes can be broken into planes, geometric figures, or even just a point. Planes only have two dimensions such as length and width. Three-dimensional shapes have length, width and height. A point would only have one dimension. While a point doesn’t take up enough space to calculate for, planes and geometric figures do. This means planes and geometric figures have an area that can be calculated.                   For each shape, there is a different formula to find its area. Three-dimensional shapes have surface area since space inside them will need to be calculated differently. The area inside a three-dimensional shape is called volume. Since calculating three dimensions is much more complex, i
