  7. Find Lesson 3.2.4

  8. Is SSa valid similarity condition? 5 9 7 14 4 8  = 3-82a T-P-S No!!! SS is NOT a valid similarity condition!

  9. Is ASAa valid similarity condition? 3-82b T-P-S Yes!!! It’s the same as AA. You don’t even need to know the side lengths if you know 2 s are . The side information is redundant. (More than you need.)

  10. AA Triangle Similarity (AA): When 2 pairs of corresponding s are , the 2 s must be . If 2 pairs of s are ,the 3rd pair must also be .

  11. Is SSSa valid similarity condition? YES IT IS! 3-84 - Linguini SSS Triangle Similarity (SSS): When 3 pairs of corresponding sides are proportional, then the s must be , an the 2 s must be .

  12. Are 2 s with the same 3 side lengths always ? 3-85 a YES!

  13. Is SSAa valid similarity condition? 3-86

  14. As you can see, even though side BC = BD , this side length is able to swivel such that 2 non-congruent sare created even though they have 2  sides and a , non-included . (SSA) ABC ABD The 2 s are NOT congruent 3-86

  15. What are the 3 similarity conditions we proved / studied? 3-87 8 min.

  16. What are the 3 similarity conditions we proved / studied? 2) SAS 3) SSS 1) AA 3 4 6 8

  17. AA Triangle Similarity (AA): When 2 pairs of corresponding s are , the 2 s must be . If 2 pairs of s are ,the 3rd pair must also be .

  18. M&M

  19. SAS Triangle Similarity (SAS): When 2 pairs of corresponding sides are proportional, & the s between those sides are , then the other correspondingsmust also be ,& the remaining pair of sides must be proportional. 8 4 3 6

  20. SSS Triangle Similarity (SSS): When 3 pairs of corresponding sides are proportional, then the s must be , an the 2 s must be .
