  1. 3-4: Adjacent Angles and Linear Pairs of Angles

  2. 3-4: Adjacent Angles, Linear Pairs • Adjacent Angles: Angles that share a common side and have the same vertex, but have no interior points in common. • We used adjacent angles yesterday with the Angle Addition Postulate P A 1 Q 2 R

  3. 3-4: Adjacent Angles, Linear Pairs • Determine whether 1 and 2 are adjacent angles • The second example illustrates a linear pair • Linear Pair: When the noncommon sides of a linear pair form a straight line. Not adjacent Adjacent Angles Not adjacent

  4. 3-4: Adjacent Angles, Linear Pairs • Name the angle that forms a linear pair with 1 • The linear pair is the straightline at the bottom (MCE) • Remove the given angle • Name the remaining angle • ACE

  5. 3-4: Adjacent Angles, Linear Pairs • Name the angle that forms a linear pair with MCH • Do 3 and TCM form alinear pair? HCE (or 4) No, they don’t make a straight line

  6. 3-4: Adjacent Angles, Linear Pairs • Assignment • Worksheet #3-4
