    How can you tell the difference between SAS and SSA? (Assume you had a problem and had to chose if it was sim. because of SAS or SSA, how would you figure it out?)

    Yo, man. This is how we do da thing. Firstly, if the triangles have 2+ matching corresponding angles, then it is similar. If it has side lengths that can be divided by a number, say X, and then match the side lengths of your other triangle, then it is similar. If it has 2 matching corresponding(see last sentence) sides, and the angle between these is the same, then it is similar. -Beauregard42. If this helps you, your welcome.

      Triangle similarity review (article) | Khan Academy (16)

      An equation is a statement with an equals sign.

      So 3 + 5 = 8 and 5x + 12 = (x / 4) + 3 are both equations,
      but 24 * 9 and 3y ≥ x - 8 are not equations.

      I believe AA, SAS, and SSS are the only triangle similarity theorems

    I thought I thought I would need a calculator for quiz 1,
    But I got a 100% Without even trying.

    These lessons do not explain SSS similar triangles very well. What lesson would help me understand the basics?

      I suppose trying the Triangle Similarity postulates/criteria lesson, or going back and reading the articles and doing all of the practice problems may help you. Ultimately, in summary, the SSS similarity is used when every side can be multiplied by a constant to get the new side, for example, if AB/XY was 4, AC/AZ was 4, and BC/YZ was 4, it would be a SSS similarity because each value can be multiplied either by 4 or 1/4 (depending on which number is larger) which is defined as the constant. I hope this helps!
