Answer: Your answer is A or
For the hexagon construction, every arc along the circle is connected, but for the equilateral triangle construction, every other arc along the circle is connected.
Step-by-step explanation: It makes sense because in the lesson you need to make 6 arcs for both hexagons and equilateral triangles. However hexagons have 2 times as much sides as triangles so to make a triangle you would have to make a line with every other arc. That means skip an arc each line you make. For A hexagon obviously because it has 6 sides you just draw the lines to connect all 6 arcs
Hope this helps!
