Geometry is the branch of mathematics that deals with the properties of space and shape. It is a fundamental subject that is studied in many different fields, from architecture to physics.
Basic Concepts
- Point: A fundamental building block of geometry, a point has no length, width, or height.
- Line: A straight path that extends infinitely in both directions.
- Plane: A flat surface that extends infinitely in all directions.
- Angle: The measure of the turn between two rays that share a common endpoint.
Formulas
Here are some basic formulas used in geometry:
- Area of a Circle: ( A = \pi r^2 )
- Circumference of a Circle: ( C = 2\pi r )
- Area of a Triangle: ( A = \frac{1}{2}bh )
- Perimeter of a Triangle: ( P = a + b + c )
