Theorem 7-2 SSS Similarity Theorem If the sides of two triangles are in proportion, then the triangles are similar. 4 ما C E B 3 12 D If AB 14 F 9 BC AC DE EF then DF AABC~A DEF 4-3 12 6 18 = Examples: → you can't say Not ~" Name the similar triangles and give the postulate or theorem that justifies your answer. A 1. DADE NAABC by AA D/80 80° B E C No length AA OR Not~ Number line: a line such that every point pairs with a number A BC D -3-2-1 012 31.0ordinate Length-the distance between 2 points on a number line Rule for finding length: subtract two coordinates, then take the absolute value of the answer (length must always be positive) * the length from A to B is written AB. AB=1-3-6-1) = 1-2/== BD=13-(-1)=141=4 Ruler Postulate: 1. Consecutive coordinates on a number line must be evenly spaced. 2. The distance between any two coordinates will be the absolute value of their difference.
