For what value of k are the lines parallel? This shows that the two lines are parallel. A line passes through points (-4, -1, 3) and (4, 4, -2). $\overline{ST}$ and $\overline{UV}$ are coplanar. Parallel planesare planesin the same three-dimensional spacethat never meet. Objects are coplanar if they lie in the same plane. Determine whether the planes are parallel, perpendicular, or neither. True or False. True or False: Two perpendicular lines are identical. Any two lines are coplanar unless they are skew. Consider a correctly functioning clock that starts ticking at noon and find the time between noon and 1:00 P.M. when the angle measure between the hands is 90degrees.

This site is using cookies under cookie policy . I have two nearsighted brothers. True or False. True or False? Two parallel lines are always coplanar. "The lines intersect and are perpendicular." This is true because the slopes of the two lines are opposite-reciprocals of each other. Note that u and v are parallel if and only if they have the same or opposite directions, which happens exactly when u and v are at an angle of 0 or . Collinear points lie on the same line. Answer: Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. The planes z =(4x+4y)=-16 \ and \ x-3 ,z=0 are not parallel, so they must intersect along a line that is common to both of them. One line passes through the points (2, 3) and (0, 4). (b) D_uf=0 when u is parallel to \nabla f. (c) The equiation 2x+5y-6=z is the equation of a line in \mathbb{R}^3 (d) \int_{0}^{2. True False Explain.
