Aregular hexagon    the construction candace performed is pretty standard for constructing a regular hexagon. but let's demonstrate why that is so.  she first, drew a circle with radius r. so every possible line from the center of the circle to the circle will be of length r. she then proceeded to draw arcs intersecting the circle using as a center, a point on the circle. so the distance between each arc and the circle will also be of length r. so you could draw a triangle using 2 adjacent arcs and the center of the circle. and all three sides of that triangle will be of length r. so that triangle would be an equilateral triangle. and since the angles in an equilateral triangle is 60 and there's 360 degrees in a circle, you can fit 360/60 = 6 equilateral triangles. and the perimeter of the group of 6 triangles will be a hexagon. and every side of the hexagon will have a length of r and every interior angle of the hexagon will have 60*2 = 120 degrees. so it will be a regular hexagon.
