Explain, if possible, how to draw two tangent lines to a circle where the tangent points are the endpoints of a diameter and the lines intersect at an exterior point. for example, given circle c, a diameter, ab¯, and a point outside of the circle, d, draw ad¯ and bd¯ to be tangent to circle c. if you don't think this is possible, explain why not.

It's not possible, as tangent lines are always perpendicular to the radius that connects the point where the line touches the circle to the center of the circle. so, if you have two lines perpendicular to the same line, the're parallel.
