Use 3.14 and write the correct answer. True or False? State True or False: The opposite sides of a parallelogram are congruent. If points are collinear, they are also coplanar. This proves that the two lines are parallel. k perpendicular m. If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle. (ii) The . Two lines that both lie in the same plane must either cross each other or be parallel so skew lines can exists only in 3 or more dimensions. Explain why or why no. For questions 3 and 4, 4 6 3 Refer to the above picture a. m23 = 45. Which values of a and b ensure that the sides of the finished frame are parallel? d. If a line is perpendicular to a plane, then it is perpendicular to all lines in that plane. Collinear points lie on the same line. Lets go ahead and recall its definition. If it is false, explain why and/or give an example that dispro, Suppose two planes are given and they intersect in a line l. Let n_{1} and n_{2} be the normals for the two planes. For what value of k is the line 2 x + k y = 3 perpendicular to the line 4 x + y = 1?

The line joining A (-2, 3) and B (-1, 5) is parallel to C (0, 5) and D (-2, y), find y. In a plane, if two lines are perpendicular to the same line, the two lines are parallel. Coplanar lines cannot be skew lines. As a recap, lines are coplanar as long they share the same space and plane. a. Below are four terms that describe different ways coplanar lines may interact: Parallel lines, segments, or rays: Lines that run in the same direction and never cross (like two railroad tracks) are called parallel. Two parallel lines do not intersect each other. Points, lines, or shapes are non-coplanar if they do not lie in the same plane. d. Through a point P not on line I, there is exactly one line through P parallel to l. 2. A ray is a subset of line that has endpoints3. a. The consecutive angles of a parallelogram are supplementary. a. Consider the plane P given by (x-2) + (y-3) + (z+2) = 0. We want the converse of that, or the same idea the other way around: If a transversal cuts across two lines to form two congruent, corresponding angles, then the two lines are parallel. In the diagram at the right, if t m and s m, then t | | s. Since t and s are each perpendicular to line m, we have two right angles where the intersections occur. 2. what even number is not a composite number 6,4,2,8, Fill in the missing angle measures in the diagram. Createyouraccount. The vector parametric equation for this line is _. Since both the vertical and horizontal lines of the grid lie on the same paper, they are coplanar points. Answer: Two lines are parallel lines if they are coplanar and do not intersect. Given two intersecting lines, L_1 = x = 4 + t, y = 2, z = 3 + 2t and L_2 = x = 2 + 2s, y = 2s, z = - 1 + 4s. explain why al b. If two planes ax + by + cz = d and Ax + By + Cz = D are parallel, then a = A, b = B, c = C and d = D. True False Explain. Parallel . The consecutive angles of a parallelogram are supplementary. 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. If they intersect, give the point of intersection. Two intersecting lines never cut each other. Show whether the lines L_1 : x= 1+t, y =2-t, z = 3t ;\quad L_2 = x = 2-s, y = 1+2s, z= 4+s are parallel, skew, or intersecting. A line extends in many directions2. _____2.the intersection of a line and a plane is a point. K is the midpoint of LN.
