Q. A playground has a dome climber for kids to play on. The geodesic dome is made of

35

triangles and

1

decahedron base. It has

26

vertices. How many of the metal rods are needed to build the dome climber? (How many edges)

Counting Triangles and Edges: Each triangle has $3$ edges, but each edge is shared by $2$ triangles. So, we need to count the edges of the triangles and then divide by $2$ to avoid double-counting. $\newline$ Calculation: $35$ triangles $\times 3$ edges per triangle $= 105$ edges. Then, $105$ edges $/ 2 = 52.5$ edges.
