The easiest way to assemble it is making 15 pentagonal pieces and 15 triangular pieces. (15 x 5 = 75, 15 x 3 =45; 75 + 45 = 120) The pentagonal pieces seem like stars, with five peaks and five "inside corners".
Take one pentagonal piece. You must put one triangular piece inside each one of these "inside corners". Then, assemble more pentagonal pieces all around the triangular ones. And then, more triangles.
