A tiling uses copies of a triangle with angles a, b and c. At each vertex, six triangles meet, and each angle a, b, c appears twice. What is 2a + 2b + 2c?

Question

Accepted Answer

360°. The six angles fill the space around the point, so they add to 360°. (This also shows a + b + c = 180°.)

A tiling uses copies of a triangle with angles a, $b$ and $c$ . At each vertex, six triangles meet, and each angle a, $b, c$ appears twice. What is $2 a + 2 b + 2 c$ ?
