Identifying Parallel Lines Worksheets Hence, When two lines are cut by a transversal, the pair ofangles on one side of the transversal and inside the two lines are called the Consecutive interior angles Parallel to \(10x\frac{5}{7}y=12\) and passing through \((1, \frac{1}{2})\). Hence, from the given figure, To find the value of c, We know that, Answer: The two pairs of supplementary angles when \(\overline{A B}\) and \(\overline{D C}\) are parallel is: ACD and BDC. Perpendicular to \(y=x\) and passing through \((7, 13)\). y = -2x + c Find an equation of the line representing the new road. The product of the slopes is -1 and the y-intercepts are different
