Here’s a complete beginner-friendly Geometry study guide
📐 GEOMETRY STUDY GUIDE (Beginner → Solid Foundation)
🔷 1. What is Geometry?
Geometry is the branch of math that studies shapes, sizes, angles, and space.
You’ll work with:
● Points
● Lines
● Angles
● Shapes (2D & 3D)
📍 2. Basic Building Blocks
✔️ Point
Exact location
No size (just a dot)
✔️ Line
Goes on forever in both directions
Written like: AB̅
✔️ Ray
Starts at one point, goes forever one way
✔️ Line Segment
Has two endpoints
📏 3. Angles
Types of Angles
● Acute: less than 90°
● Right: exactly 90°
● Obtuse: between 90° and 180°
● Straight: 180°
Key Relationships
● Complementary: add to 90°
● Supplementary: add to 180°
