Help understanding how to construct a circle and a tangent to the circle using a compass and straightedge. • Draw three random points on your paper. • Construct the circle through these three points. • Determine the circle's center. • Construct a tangent to the circle, using one of the original three points as the point of tangency.

    construct the perpendicular bisectors of each side and find where they intersect this will be the center of your circle|dw:1353083511618:dw|

    |dw:1353083601083:dw| draw the radius from the center to one of your points say point 3 in this case.

    your tangent will be perpendicular to the radius at point 3
