Chapter 2 42 Glencoe Geometry 2-7 Study Guide and Intervention Parallel Lines and Transversals Transversal Angle Pair Relationships A line that intersects two or more other lines at two different points in a plane is called a transversal. In the figure below, line t is a transversal. Two lines and a transversal form eight angles.

Example: If m∠1 = 3 x + 15, 2 4 - 5, and 3 5y, find the value of x and y. p ∥ q, so m∠1 = m∠2 Lesson 2-7 Segment Addition Two basic postulates for working with segments and lengths are the Ruler Postulate, which establishes number lines, and the Segment Addition Postulate, which describes what it means for one point to be between two other points.

The lengths of MN and RS are written as MN and RS. When you measure a segment, the precision of the measurement is half of the smallest unit on the ruler. -Example 1 Find the length of MN. cm I Find the measurement of each segment.
