Which of these tools or constructions is used to inscribe a square inside a circle? a. parallel line through a point b. equilateral triangle c. perpendicular bisector d. rotational symmetry

One way to inscribe a square in a circle would be to draw two perpendicular diameters and connect the intersections of the diameters with the circle. To draw a diameter, draw the perpendicular bisector of any chord on the circle. To draw a second diameter, perpendicular to that one, draw the perpendicular bisector of the first diameter.
To summarize: one method of inscribing a square in a circle is to draw any chord on the circle, draw the perpendicular bisector of that chord, then draw the perpendicular bisector of the perpendicular bisector. Connect the intersections of the two perpendicular bisectors with the circle to fo the desired square. This method involves only the perpendicular bisector, so C is the answer.
Hope this explanation helps, if it does, I’d appreciate being marked “brainliest”

Bi’m pretty sure hope it works
