Indicate whether the following statements are True or False. The lines r = (5,3,2) + s(1,-1,-1) and r = (6,2, 1) + 1(-1,1,-2) intersect at the point (6, 2,1). Objects are coplanar if they lie in the same plane. If two planes intersect, then their intersection is a [{Blank}]. True or false Flashcards Coplanar lines that are not parallel must intersect or cross each other. b. 2. The points on a line can be paired one to one with real numbers. y = 0.15x + 0.79 0.11x - y = -0.85. For example, see at second image. True b. True or False: Two parallel lines are two lines that do not intersect. 200 The slope of any line parallel to Y=1/5x+2 What is 1/5? If they intersect, give the point. Solution: The two lines are parallel as they meet one of the properties of parallel lines "when the alternate interior angles are equal, the lines are parallel". Complementary angles are adjacent angles. b. 1) Two or more lines that lie in the same plane and never intersect each other are known as parallel lines. Two lines are coplanar if they both line in the same plane. C) Three or more points must be collinear.
