i dont get most of this stuff

Try to practice upon it and you might get it, or just use khan academy's practice a lot. Hope it helps

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?)

SAS means that the angle is in between the two sides in question. SSA means the angle is not in between.

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.

Review the triangle similarity criteria and use them to determine similar triangles.

What are the triangle similarity criteria?


AA	Two pairs of corresponding angles are equal Two triangles. One triangle is smaller than the other. Both triangle have two angles that are congruent.
SSS	Three pairs of corresponding sides are proportional Two triangles. One triangle is smaller than the other. The smaller triangle has side lengths a, b, and c. The larger triangle has side lengths a times k, b times k, c times k.
SAS	Two pairs of corresponding sides are proportional and the corresponding angles between them are equal Two triangles. One triangle is smaller than the other. The smaller triangle has side lengths a and b. The larger triangle has side lengths a times k and b times k. The angle between the side lengths of the smaller triangle is congruent to the angle between the side lengths of the larger triangle.

  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.
