Question

9. Which lines are parallel if m<4 = m<5? Justify your answer.

Answer 1

Answer:

lines r and s

Step-by-step explanation:

we know that

Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

When the lines are parallel, the alternate interior angles are equal

so

In this problem

If lines r and s are parallel

then

m∠4=m∠5 ----> by alternate interior angles
