Prove that the perpendicular bisector of any chord of a circle contains the center of the circle. (b) Trace partway around a cup or saucer to draw a circular arc. Then explain how to construct the center of the arc. (Hint: use part (a) twice!) Let the chord of a circle be AB overbarAB. The perpendicular bisector of AB overbarAB must intersect the circle exactly enter your response here times.

Developing Proof Complete the flowchart proof or write a paragraph proof of the Perpendicular to a Chord Conjecture: The perpendicular from the center of a circle to a chord is the bisector of the chord. Given: Circle $O$ with chord $\overline{C D}$, radii $\overline{O C}$ and $\overline{O D}$, and $\overline{O R} \perp \overline{C D}$ Show: $\overline{O R}$ bisects $\overline{C D}$ Flowchart Proof (figure not copy)

2. Proof by contradiction (indirect proof) Prove by contradiction the following theorem: If there is a perpendicular bisector of a given chord AB, then this chord passes through the center of the circle ⊙O. Hint: This theorem should look familiar to you. Use your notes to help you figure out what the first line of your argument should be. (a) 1st line: (b) Circle one: T / F With an indirect proof, your Last line should create a logical contradiction. 2nd line: If you assume the hypothesis is true and that your conclusion is false in the first line, then from here you will need to show that there exists a contradiction. Use parts a-b to help guide you to a successful proof by contradiction. Statements | Reasoning

Prove the stated theorem. If a line is drawn through the center of a circle perpendicular to a chord, then it bisects the chord and its minor arc. See Figure 6.37 on page 288 (NOTE: The major arc is also bisected by the line.)
