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.
Circle: 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.
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 sha...
