Transversals and Corresponding Angles

Slide1 : Parallels § 4.1 Parallel Lines and Planes § 4.4 Proving Lines Parallel § 4.3 Transversals and Corresponding Angles § 4.2 Parallel Lines and Transversals § 4.6 Equations of Lines § 4.5 Slope

Slide2 : Transversals and Corresponding Angles You will learn to identify the relationships among pairs of corresponding angles formed by two parallel lines and a transversal.

Slide3 : Transversals and Corresponding Angles When a transversal crosses two lines, the intersection creates a number of angles that are related to each other. Note 1 and 5 below. Although one is an exterior angle and the other is an interior angle, both lie on the same side of the transversal. Angle 1 and 5 are called __________________. corresponding angles Give three other pairs of corresponding angles that are formed: 4 and 8 3 and 7 2 and 6
