Question 2

Fill in the blanks for the paragraph proof for . Given: , , and Prove: Proof: All radii of a circle are congruent, so , and since and , then are right triangles by the __________ congruency theorem. The corresponding sides of the triangles, and , are congruent, so ZV = YX. Thus, we know that 2ZV = 2YX by the multiplication property of equality. By a congruency theorem that states, “if a diameter of a circle is perpendicular to a chord, then the __________,” bisects and bisects , so VU = 2ZV and XW = 2YX. Therefore, we can conclude that VU = XW, or . A. HL (Hypotenuse-Leg) . . . diameter bisects the chord and its other chord B. SSS (Side-Side-Side) . . . diameter bisects the arc and its measurement C. HL (Hypotenuse-Leg) . . . diameter bisects the chord and its arc D. ASA (Angle-Side-Angle) . . . chord but not the diameter Please select the best answer from the choices provided
