Introduction to Pyramid
1. What is a Pyramid?
A pyramid is a solid 3D shape with a flat base that is a polygon, and triangular sides that meet at a single point called the apex (or top).
Hence, A pyramid is a 3D solid shape that has:
a. A Polygon base (like a square, triangle, or rectangle),
b. Triangular faces that meet at a common point called the apex (or vertex).
2. 🏛️ Examples in Real Life:
- The Pyramids of Egypt (Square base),
- A tent (Triangular base),
- An ice cream cone with a flat polygonal base.
3. Parts of a Pyramid:
- Base: The flat bottom surface (can be any polygon).
- Lateral Faces: The triangle faces that meet at the apex.
- Apex (Vertex): The top point where all triangle faces meet.
- Slant Height (l): The diagonal height from the base edge to the apex.
- Height (h): The vertical distance from the base center to the apex.
