Answer:

[tex]\bar{AD}\parallel \bar{BC}[/tex]

Step-by-step explanation:

If [tex]m\angle 4=m\angle8[/tex], then [tex]m\angle4[/tex] and [tex]m\angle4[/tex] are alternate interior angles.

This means that line segment AC is a transversal.

This implies that line segment AD is parallel to line segment BC.

The second choice is the correct answer.

Answer:

The correct answer is second option.

AD ║ BC

Step-by-step explanation:

Alternate interior angles in a parallel lines are equal.

From the figure we can see quadrilateral ABCD.

It is given that m<8 = m<4

Consider the line segment AD and BC,and AC is a traversal on these lines, m<8 and m<4 are alternate interior angles, which is equal.From this we can conclude that, AD║ BC
