Understanding Euclidean Geometry
Points, Lines and Planes
- Points: Represent specific locations with no size
- Lines: Made up infinite points extending in both direction
- Planes: Flat surface extending infinitely in all 2D directions
- Line segment: Defined portion between two points (AB)
Angles Explained
- Right Angle: Measures 90 degrees
- Acute Angle: Less than 90°
- Obtuse Angle: Between 90° and 180°
