It had been 11 years since Noah Hoffman ’22 had taken a math class when he arrived on campus this fall. A Resumed Undergraduate Education student and former Olympic cross-country skier, Hoffman ...

For an octahedron, the angles of the 4 triangles add up to equal 240 degrees, and for an icosahedron there are 300 degrees where the 5 triangles meet at each vertex.

An angle is formed when two straight lines, or rays, meet at a point, called a vertex. Angles are measured in degrees.

If we translate one vertex at a time we can see that vertex a has translated 3 squares down and 3 squares to the left. When a shape is translated all of the vertices stay aligned.
