Match the following reasons with the statements given. given: r = q as = at prove: rs = qt. 1. ∠r = ∠q, as = at two ∠'s supplementary to equal ∠'s are = 2. ∠5 = ∠6 exterior sides in opposite rays 3. ∠4, ∠5 are supplementary and ∠6, ∠7 are supplementary aas 4. ∠4 = ∠7 base ∠'s of isosceles triangle are = 5. triangle ras congruent to triangle qat given 6. rs = qt cpcte
