Activity 1 Bases and Names of Pyramids
Learn about triangular pyramids.
A solid figure with a triangular base and triangle-shaped sides that meet at
a common vertex is called a triangular pyramid. A triangular pyramid has
four vertices, six edges, and four faces.
4 vertices 6 edges 4 faces
1 . Use Magformers to make a square pyramid.
Then answer the questions.
What you need: Magformers
a. How many vertices does it have?
b. How many edges does it have?
c. How many faces does it have?
d. Do all the faces have the same shape?
Discuss the similarities and differences between a triangular pyramid and
square pyramid.
