My son is stuck with homework.
hepta=7, actually... use the triangles to make a normal hex(6)agon and then remove one of the triangles. put the triangle near one of the edges of the gap and it should createan irregular heptagon (also known as a "septagon")
HEPTA IS 7, NOT 6. YOULL NEED 7 ISOSCELES TRIANGLES EACH WITH ONE ANGLE OF 51.4 DEGREES.
Hepta=6 right? If yea then put the tip of the triangles in the center
No he has to make a 7 sided heptagon with 6 triangles.
hecto is 6
