  1. 4-3: Transversals and Corresponding Angles

  2. 4-3: Transversals and Corresponding Angles • Corresponding Angles: An interior and exterior angle formed by two lines and a transversal, where both angles lie on the same side as the transversal • Angles 7 & 8 below are corresponding angles (both are in the upper-right corner)

  3. 4-3: Transversals and Corresponding Angles • Example: Name a pair of corresponding angles 1 & 5 2 & 6 4 & 7 3 & 8

  4. 4-3: Transversals and Corresponding Angles • Postulate 4-1: If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

  5. 4-3: Transversals and Corresponding Angles • Which figures are congruent to 1?Explain your answers. 3 (corresponding angles) 5 (vertical with 3) 7 (vertical angles) 9 (corresponding angles) 11 (corresponding with 9) 13 (vertical with 11) 15 (vertical with 9)

  6. 4-3: Transversals and Corresponding Angles • Find the measure of each numbered angle. • 11 • 12 • 13 • 14 • 15 = 124˚ = 98˚ = 82˚ = 124˚ = 98˚

  7. 4-3: Transversals and Corresponding Angles • Assignment: Worksheet #4-3
