On the circle you created in Question 1, draw the chords , , , and , and label their lengths. This construction results in quadrilateral BCDE inscribed in circle A. Label the measures of the interior angles,∠B, ∠C, ∠D and ∠E for quadrilateral BCDE.

Now construct the central angles ∠CAB, ∠DAC, ∠EAD and ∠BAE for circle A by drawing four radii on the circle. Label the measure of each central angle. When you’re through, consider hiding the radii so you can get a clear picture of the angles you created. Be careful not to delete the angle measures.
