  1. 1. Two figures with the same shape and size are:
    • (a) similar
    • (b) parallel
    • (c) congruent
    • (d) equal in area only
  2. 2. The symbol for congruence is:
    • (a) =
    • (b) ~
    • (c) >
    • (d) ≅
  3. 3. Which criterion uses three equal sides?
    • (a) SSS
    • (b) ASA
    • (c) SAS
    • (d) RHS
  4. 4. In SAS, the equal angle must be the:
    • (a) largest angle
    • (b) included angle
    • (c) right angle
    • (d) exterior angle
  5. 5. What does congruent mean?
  6. 6. Name the four triangle congruence criteria.
  7. 7. What does it mean for two triangles to be congruent, and why do we use criteria?

  1. 1. (c) congruent — Same shape and size means congruent.
  2. 2. (d) ≅ — ≅ means 'is congruent to'.
  3. 3. (a) SSS — SSS = Side-Side-Side.
  4. 4. (b) included angle — The angle must lie between the two sides.
  5. 5. Having exactly the same shape and size.
  6. 6. SSS, SAS, ASA and RHS.
  7. 7. Two triangles are congruent when they have exactly the same shape and size, so that one could be placed exactly over the other; this means all three pairs of corresponding sides and all three pairs of corresponding angles are equal. Checking all six parts every time would be tedious, so we use congruence criteria — short sets of conditions that guarantee congruence. If just enough matching parts agree (for example three sides, or two sides and the included angle), the triangles must be congruent, and then every other corresponding part is automatically equal too.
