Circle Constructions
1) Construct a circle and two radii. Measure the length of the radii. What do you notice?

2) Construct a circle from a diameter. Also construct a radius and a chord that is not a diameter. Measure the length the chord, diameter, and one radius. What do you notice?
3) Construct a circle with a central angle and an inscribed angle. Make a conjecture on how the measure the central angle is related to measure of the inscribed angle. Now measure both angles. What do you notice?
4) Construct a circle from a diameter. Construct an inscribed angle that has endpoints on the diameter. Measure the inscribed angle. What do you notice?
5) Construct two tangent lines from a point outside the circle. Measure the angles. What do you notice?
