True or false: some pairs of skew lines are also parallel. True or False. Lets go ahead and recall its definition. False. The planes 4x - 4y - 5z = 19 and y - 5x + 5z = -17 are not parallel, so they must intersect in a line. Learn about the geometric concept of coplanar lines. When two or more than two lines are in the same plane is defined as a coplanar line. Fun fact: not only are these lines coplanar, but they are also parallel. Determine whether the following statement is true or false in 3-dimensional space: Two lines parallel to a third line are parallel to one another as well. L1: (-4, 4) and (1, 9) L2: (-4, 5) and (2, -1). segment P lik 13. . y = - 2 /3 x + 8 y = 2 / 3 x - 5, True or False: These are the questions, True or False for (11) of them: 1.
