Lena is constructing a regular hexagon inscribed in a circle. she begins by drawing a line and labeling a point on the line as point a. she uses her compass to construct a circle with point a as the center, labeling the points where the circle intersects the line as points b and c. without changing the compass opening, she constructs a circle with point b as the center. what step should be her next step? without changing the compass opening, construct a circle with point c as the center. draw a line through point a and either of the two points where the circles intersect. draw a line through the points where the two circles intersect. increasing the compass opening, construct a circle with point c as the center.
