A 7 sided heptagon contains 5 triangles.
Seven
depends on the side of the triangles?
A heptagon has seven sides, so a regular heptagon has seven lines of symmetry (they run from each vertex to the middle of the opposite side).

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 heptagon is a polygon with 7 sides.
A heptagon has seven sides.
depends on the side of the triangles?
In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.
A heptagon has seven sides, so a regular heptagon has seven lines of symmetry (they run from each vertex to the middle of the opposite side).
