Match the reasons with the statements. Complete the proof for Theorem 3-16 above, with the information given. Given: m1 = m2 Prove: l | | m Plan: Same as Theorem 3-15 1.m∠1 = m∠2 a:Substitution
2.m∠1 = m∠3
B:If corresponding angles are equal, then lines are parallel. 3.m∠2 = m∠3
c:Vertical angles are equal.
4.l||m

60 + 3

63

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is
