Using the diagram at right, determine the following values: x = _ y = _ Boot-Up 10.2.13 / 6 min. SSS Triangle Similarity (SSS): When 3 pairs of corresponding sides are proportional, then the s must be , an the 2 s must be . SAS Triangle Similarity (SAS): When 2 pairs of corresponding sides are proportional, & the s between those sides are , then the other correspondingsmust also be ,& the remaining pair of sides must be proportional. What are the 3 similarity conditions we proved / studied? 2) SAS 3) SSS 1) AA 3 4 6 8 What are the 3 similarity conditions we proved / studied? 3-87 8 min. (SSA) ABC ABD The 2 s are NOT congruent 3-86 Is SSAa valid similarity condition? 3-86Īs 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 . Is SSSa 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 .Īre 2 s with the same 3 side lengths always ? 3-85 a YES! If 2 pairs of s are ,the 3rd pair must also be . (More than you need.)ĪA Triangle Similarity (AA): When 2 pairs of corresponding s are , the 2 s must be . You don’t even need to know the side lengths if you know 2 s are . Is ASAa valid similarity condition? 3-82b T-P-S Yes!!! It’s the same as AA. Is SSa valid similarity condition? 5 9 7 14 4 8 = 3-82a T-P-S No!!! SS is NOT a valid similarity condition! If BD = 6, DA = 2, & BC = 15, what is the length of side x?
