If six equilateral triangles are placed side by side so that only two sides of each triangle touch one of the other triangles what shape is formed?

We are thinking circle?

But a circle is curved, and triangles has straight edges.

* a circle has . . .

To determine the shape formed, we can visualize the given situation and analyze the resulting figure:

1. Start with one equilateral triangle.
2. Place another equilateral triangle next to it, so that two sides of each triangle are touching. Now, we have two adjacent equilateral triangles.
3. Repeat step 2 four more times, adding four more equilateral triangles next to the existing ones.

By following these steps, we get a figure made up of six equilateral triangles arranged side by side. Each triangle contributes two sides touching another triangle, according to the given conditions.

Now, let's analyze the resulting figure:
- The six equilateral triangles create a hexagonal shape. A hexagon is a polygon with six sides.
- Since each triangle is equilateral, the hexagon formed by combining these triangles is also equilateral.

Therefore, the shape formed by placing six equilateral triangles side by side, with only two sides of each triangle touching another triangle, is a regular hexagon. It is not a circle.
