Question

Which of the following pairs is pair of interior formed by two parallel lines and on the same side of the transversal?

• A. ${30}^0,{60}^0$
• B. ${30}^0,{150}^0$
• C. ${60}^0,{130}^0$
• D. ${50}^0,{120}^0$

Answer 1

The correct option is B ${30}^0,{150}^0$

Sum of interior formed by two parallel lines and on the same side of the transversal line is $={180}^{\circ }$

Hence, ${30}^{\circ },{150}^{\circ }$ is the correct answer.
