3 cards from this section. Quick, good the night before a test.
What is Euler's Formula?
It involves faces, vertices, and edges.
How many faces does a cube have?
Think of how many flat surfaces it has.
What relationship does Euler's Formula describe?
Consider what elements of a polyhedron it connects.
True or False: A cube has more edges than vertices.
Count the vertices and edges carefully.
A polyhedron has 12 faces and 20 vertices. How many edges does it have?
Apply Euler's theorem here.
Using Euler's Formula, verify if a shape with 6 faces, 12 vertices, and 7 edges is a polyhedron.
Test against the Euler’s formula condition.
