Given: circle m with inscribed and congruent radii jm and ml prove: m = what is the missing reason in step 8? statements reasons 1. circle m with inscribed ∠kjl and congruent radii jm and ml 1. given 2. △jml is isosceles 2. isos. △s have two congruent sides 3. m∠mjl = m∠mlj 3. base ∠s of isos. △are ≅ and have = measures 4. m∠mjl + m∠mlj = 2(m∠mjl) 4. substitution property 5. m∠kml = m∠mjl + m∠mlj 5. measure of ext. ∠ equals sum of measures of remote int. ∠s of a △ 6. m∠kml =2(m∠mjl) 6. substitution property 7. 7. central ∠ of △ and intercepted arc have same measure 8. 8. ? 9. 9. multiplication property of equality reflexive property substitution property base angles theorem second corollary to the inscribed angles theorem mark this and return
