  1. Complementary Angle
    X+Y= 90 degree
    If "Y" equals 40 what is "X"
    • X+Y= 90
    • X+40= 90, X+40-40= 90-40=50degrees
  2. Supplementary Angle
    X+Y=180
    if "Y" equals 25 what is "X"
    • X+Y=180
    • X+25=180, X+25-25=180-25=155degrees
  3. Associative Property Of Addition
    A+(B+C)=(A+B)+C
    5+(6+0)=(5+6)+0
  4. Associative Property of Multiplication
    A(BC)=(AB)C
    4(3x)=(4*3)x
  5. Commutative Property of Addition
    A+B=B+C
    4+(3+x)=4+(x+3)
  6. Commutative Property of Multiplication
    A*B=B*A
    4(3x)=(3x)4
  7. Distributive Property
    A(BC)=AB+AC
    4(3+x)=4*3+4*x
  8. Additive Inverse Property
    a+(-a)=0
    • -5/8+5/8=0
    • or
    • 5+(-5)=0
  9. Multiplicative Inverse Property
    a(1/a)=1
    • 40(.025)=1
    • or
    • 5*1/5=1
  10. Additive Identity Property
    A+0=A
    • A+B+0=A+B
    • or
    • 5+0=5
  11. Multiplicative Identity Property
    A(1)=A
    • 1(A+B)=A+B
    • or
    • 5*1=5
