3.6. Same Side Interior Angles http://www.ck12.org
In 4-5, use the given information to determine which lines are parallel. If there are none, write none. Consider each
question individually.
4.^6 AF D and^6 BDFare supplementary
5.^6 DIJ and^6 F JIare supplementary
For 6-11, what does the value ofxhave to be to make the lines parallel?
6.m^63 = ( 3 x+ 25 )◦andm^65 = ( 4 x− 55 )◦
7.m^64 = ( 2 x+ 15 )◦andm^66 = ( 3 x− 5 )◦
8.m^63 = (x+ 17 )◦andm^65 = ( 3 x− 5 )◦
9.m^64 = ( 3 x+ 12 )◦andm^66 = ( 4 x− 1 )◦
10.m^63 = ( 2 x+ 14 )◦andm^65 = ( 3 x− 2 )◦
11.m^64 = ( 5 x+ 16 )◦andm^66 = ( 7 x− 4 )◦For 12-13, determine whether the statement is true or false.
- Same side interior angles are on the same side of the transversal.
- Same side interior angles are congruent when lines are parallel.
