Create a Square Inscribed in a Circle

1) Use the Line toolToolbar Image to create a line between the center of the circle and the point on the circle. This could be ANY point on the circle. Using the given point will match your square up with the red square shown. 2) Use the Intersect toolToolbar Image to mark the point where that line and the circle intersect. 3) Create a line perpendicular to the line from step 1 that goes through the center of the circle. 4) Use the Intersect toolToolbar Image to mark the points where this line intersects the circle. 5) Use the Polygon toolToolbar Image to create your square from the four points on the circle. 6) Use the Angle Measure toolToolbar Image and the Distance toolToolbar Image to verify that the result is a square.
