Well, isn't that just a happy little challenge! To make a heptagon out of six equilateral triangles, you can start by arranging the triangles in a circular pattern with their edges touching. Then, you can add a seventh equilateral triangle on top to complete the shape. Remember, there are no mistakes, just happy accidents in art!
A parallelogram.
A heptagon is a shape with 7 sides. A regular heptagon is the normal version you will see however an irregular heptagon is any shape with 7 sides.To see it visually, use the triangles to create a normal hexagon (6 sides), remove one of the triangles and put it next to one of the edges near the gap.If done correctly this will create a 7 sided object - an irregular heptagon.
Equilateral triangles are also equiangular.
Construct/make a tetrahedron, which is three-dimensional.
No.
Rhombus
draw a big triangle then make a line halfway through it
a larger equilateral triangle
draw a hexogon and make six triangles no more than six unless you are doing a different math problem than i am.
No but they will make a hexagon
Four equilateral triangles make up another equilateral triangle.
