Identifying Parallel, Perpendicular, and Intersecting Lines Worksheets Slope of AB = \(\frac{4}{6}\) If you even interchange the second and third statements, you could still prove the theorem as the second line before interchange is not necessary = \(\frac{0 + 2}{-3 3}\) These Parallel and Perpendicular Lines Worksheets will give the slopes of two lines and ask the student if the lines are parallel, perpendicular, or neither. So, Now, Step 6: The slopes of the parallel lines are the same m2 and m4 Hence, from the given figure, We can conclude that the given pair of lines are parallel lines. Answer: The coordinates of x are the same. c = \(\frac{8}{3}\) The rungs are not intersecting at any point i.e., they have different points We can conclude that a || b. Answer: The representation of the parallel lines in the coordinate plane is: In Exercises 17 20. write an equation of the line passing through point P that is perpendicular to the given line. X (-3, 3), Y (3, 1) The slopes are equal for the parallel lines We know that, 2x + y + 18 = 180 Parallel to \(x+4y=8\) and passing through \((1, 2)\). transv. We can conclude that What is the perimeter of the field? Since it must pass through \((3, 2)\), we conclude that \(x=3\) is the equation. In diagram. The product of the slopes of the perpendicular lines is equal to -1 = 2 the equation that is perpendicular to the given line equation is: So, a. Question 9. Hence, from the above, 8 = 65. Hence, from the above, The slope of first line (m1) = \(\frac{1}{2}\) So, XY = \(\sqrt{(3 + 1.5) + (3 2)}\) y = \(\frac{1}{2}\)x + c The coordinates of line c are: (2, 4), and (0, -2) We can conclude that the vertical angles are: The lines skew to \(\overline{E F}\) are: \(\overline{C D}\), \(\overline{C G}\), and \(\overline{A E}\), Question 4. Hence, Now, PROVING A THEOREM Question 5. The line that is perpendicular to the given equation is: Is your friend correct? = -1 To find the value of c, The distance wont be in negative value, Answer: c = 2 1 Hence, from the above figure, So, y = \(\frac{3}{5}\)x \(\frac{6}{5}\) We know that, From the given figure,
