Welcome to Basic Geometry!
Geometry is all around us in the real world. It is the study of points, lines, angles, surfaces, and solids. If you have ever tried to fit a bookshelf into a corner or figured out the shortest path between two places, you've applied geometric principles. Let's dive into some exciting topics!
1. Points and Lines
- Point: A location in space without any size or dimension. - Line: Extends indefinitely in both directions without any end. Lines are one-dimensional.
2. Angles
Angles are formed when two lines meet at a point. They are measured in degrees (°). You'll encounter terms like right angle (90°), acute angle (< 90°), and obtuse angle (> 90°).
3. Shapes and Their Properties
Common shapes include triangles, squares, circles, and rectangles. Learning their properties, such as area and perimeter, is fundamental in geometry.
