Geometry is a branch of Mathematics used to draw and measure figures.
The word geometry refers to field measurement. We learn how to draw various figures in geometry, such as rectangles, squares, triangles, cones, cylinders and spheres, etc.
Basic Elements of Geometry
Point
- The basic element of geometry is the point.
- A point has no length, breadth, or height.
Line
- A line has only length, not breadth.
- A line segment can be straight or curved.
- A line segment can contract by joining two points.
- The shortest line segment which joins two prints is called the straight line segment.
- Figures can be drawn by joining line segments.
- Some geometrical shapes can be drawn by joining straight line segments, curved line segments, and by joining both straight and curved line segments.
Types of Geometry Shapes
In geometry, there are two types of shapes:
Open Figures
Open figures are open from all sides.
Closed Figures
Closed figures are closed from all sides
Parallel to the open and closed figures, some plane figures and solid shapes are discussed below.
Plane Figures
Plane figures have length and breadth and are drawn by joining line segments. Triangles, quadrilaterals, rectangles, squares, and circles are some examples of plane figures.
Solid Shapes
Solid shapes have length, breadth and height. Cubes, cuboids, cylinders, spheres are some examples of solid shapes.
