Prove triangles similar by SSS and sas Tina Collins, Roscommon High School, Roscommon, MI
SSS Similarity • Side-Side-Side (SSS) Similarity Theorem: If the corresponding side lengths of two triangles are proportional, then the triangles are similar.
SAS Similarity • Side-Angle-Side (SAS) Similarity Theorem: If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles are similar.
Time out for fun… (http://mathjokes4mathyfolks.wordpress.com/page/2/) • Someday, I hope to use my ability to make up funny names to write a bestseller under a pseudonym. (At this point, putting my real name on a book would surely lead to negative sales.) Some of my ideas are: • Putting the Pieces Together, by Lois Carmen Denominator • Step by Step, by Al Gorithm • The Longest Side, by HyPotenuse • Much Ado About Nothing, by Zee Row • Calculus for Tan Gents, by Anne T. Derivative • Nothing to See Here, by M. T. Set • Mirror, Mirror, by Reif Lection • Below the Line, by Dee Nominator • Pushing My Buttons, by Cal Culator • I Lost My Parrot, by Polly Gon • Three Dimensions, by Polly Hedron • What My x Got in the Break-Up, by Al Jabra • Local Extremes, by Max Imum and Minnie Mum • Out In Front, by Lee Ding Coefficient
Example • Is either ∆RST or ∆XKZ similar to ∆ABC?
Examples • Find the value of xthat makes the triangles similar.
