Draw Tangents from a point outside the circle
1) Using the Line tool, draw line CD and line CE. Point D and E are points of tangency so you are drawing tangent lines.
2) Using the Segment tool, draw the radii to point D and E, the points of tangency.
3) Using the angle measurement tools and the Distance or Length tool, to investigate the quadrilateral you have just drawn.
4) Record what you have learned on the Note Sheet.
