This presentation illustrates various congruency rules in triangles. Useful for class vii to x

  • 1
    Proving Triangles Congruent
  • 2
    The Idea of a Congruence Two geometric figures with exactly the same size and shape.
  • 3
    How much do you need to know... , about two triangles 000 to prove that they are congruent?
  • 4
    Corresponding Parts In Lesson 4.2, you learned that if all six pairs of corresponding parts (sides and angles) are congruent, then the triangles are congruent. AABC = A DEF
  • 5
    Do you need all six ? NO ! SSS SAS ASA A AS
  • 6
    Side-Side-Side (SSS) 2. BC 3. AC AABC DEF
  • 7
    Side-Angie-Side (SAS) *AABC A DEF O included angle
  • 8
    Included Angle The angle between two sides
  • 9
    Y s Included Angle Name the included angle: YE and ES ES and Y S and YE
  • 10
    Angle-Side-Angle (ASA) 2, AB DEO AABC = A DEF include
  • 11
    Included Side between two angles The side HI
  • 12
    Included Side Name the included angle: Y s ZY and ZE ZE and Z S LS and ZY YE ES SY
  • 13
    Angle-Angie-Side (AAS) 2. z B AABC = A DEF O Non-included side

    Warning: No SSA Postulate There is no such thing as an SSA B postulate! c D NOT CONGRUENT
  • 15
    Warning: No AAA Postulate There is no such thing as an AAA postulate! c NOT CONGRUENT
  • 16
    The Congruence Postulates G-SSS correspondence ASA correspondence SAS correspondence AAS correspondence AAA c

    Name That Postulate SAS (when possible) ASA sss
