The main difference the line and the line segment is that lines do not have endpoints while line segments have endpoints. Help them gain a better comprehension in identifying, drawing and labeling points, lines, rays, and line segments. Draw the symbol mathematicians use to represent "parallel lines." In the given figure, O and N are not end points of line segment OP. All equilateral triangles are similar. 1) Reflection across x = 1 2) . By this definition, the diagonal connecting Line segments connecting the center of rotation to a point on the pre-image and the corresponding point on the image have equal length. Graph each line to verify your answer. Like adjacent lanes on a straight highway, two parallel lines face in the same direction, continuing on and on and never meeting each other. Definition: A straight line which links two points without extending beyond them. See Ch. This exercise containing multiple-choice questions will immensely enhance the understanding of lines, rays, and line segments, as students are required to identify the correct figure from a set of four given options. b.
