  1. Warm-up • Solve. • 16 + 4 x 2 – 7 x 3 • 2. 16 ÷ 4 x 2 – 8 + 2

  2. NOTES - Angles Types of Angles: Naming Angles – Four ways: 1. Use angle number alone <2 2. Use middle letter alone <G 3. Use letter in ABC order, vertex in the middle <FGH 4. Use letters in reverse ABC order, vertex in the middle <HGF

  3. NOTES - Angles Complementary Angles: Sum equals 90° Supplementary Angles: Sum equals 180°

  4. EXAMPLES - Angles Name the angle to the right four ways 1 <3, <S, <RST, <TSR Classify the angle as acute, obtuse, right, or straight. OBTUSE 2 4 STRAIGHT 3 5 RIGHT ACUTE

  5. EXAMPLES - Angles Classify the pair of MARKED angles as complementary, supplementary, or neither. 8 6 COMPLEMENTARY SUPPLEMENTARY 7 9 SUPPLEMENTARY COMPLEMENTARY

  6. EXAMPLES - Angles Find the missing Measurement. X X 10 12 121° 74° 180 – 121 = 59° 90 – 74 = 16° 25° 11 X 90 – 25 = 65°
