A pyramid is a solid figure with a polygonal base and triangular faces that meet at a single point called an apex. It has a base, lateral faces that are triangles, lateral edges, and an altitude. The characteristics are that the lateral edges are congruent, lateral faces are congruent isosceles triangles, and the altitude meets the base at its center. Pyramids can be classified by their base as right, triangular, pentagonal, or hexagonal pyramids.

3. What is pyramid?
• A pyramid is a solid figure which is bounded
by a polygonal base and a number of triangles
as its lateral faces which meet at a single point
called an apex.

Vertex

6. What are the characteristics of
pyramid?
• 1) All lateral edges are congruent.
• 2) All lateral faces are congruent isosceles
triangles.
• 3) The altitude meets the base at its center.
• 4) Lateral faces meet at a single point called
an apex/ vertex

7. Types of Pyramid
• Right Pyramid
• Triangular Pyramid
• Pentagonal Pyramid
• Hexagonal Pyramid

8. SUMMARY
• So, a pyramid is a solid figure with a polygonal
base and triangular faces that meet at a
common point, and the types is classified by
the base
