Introduction to Geometry
Geometry is an essential field of mathematics that involves studying sizes, shapes, and dimensions of different figures and objects. Let's dive into some basic concepts you need to understand:
- Point: A location in space, a point has no size or dimension.
- Line: A straight one-dimensional figure extending infinitely in both directions.
- Plane: A flat, two-dimensional surface that extends infinitely.
Shapes and Figures
Here are some common geometric figures you might encounter:
- Circle: A round shape with all points equidistant from the center.
- Triangle: A three-sided polygon.
- Square: A four-sided polygon with equal sides and right angles.
