|Class 6 Maths Basic Geometrical Ideas||Curves|
Curve can be defined as the continuous movement of points in any and every direction. It means that all possible shapes can be classified as curves because all the shapes are formed by the movement of the points in single or multi dimension.
Regarding the above definition, is straight line a curve?
In general life, no straight line is not a curve. We define curve as an entity that is not straight.
In mathematics, even a straight line is a curve. We define curve as the movement of points.
Example of curves:
Types of Curve:
Position in a closed curve:
Referring to the above image, it represents a circular cricket ground (i.e. a closed curve). In a closed curve, there are three position.
A batsman playing shots while a cricket match, he can hit three types of lofted shots in that ground, six outside the field (i.e. exterior of the curve – shown by a white line), lofted shot inside the field (i.e. interior of the curve – shown by red line) or six on the boundary ropes (i.e. on the curve – shown by green line).
Question: Draw a diagram to illustrate the following: Open Curve, Closed Curve
