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.
connect the points to make a triangle|dw:1353083369461:dw|
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
Thank you so so so much! this is exactly what i needed! thank you!
