Which equation results from applying the secant and tangent segment theorem to this figure? x(x 2) = (x 4) x(x 4) = (x 2) x(x 4) = (x 2)2 x(2x 4) = (x 2)2.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
