SAS Theorem & Similarity

Interact with the applet below for a few minutes. Given : 1. The black angle for both triangle is same. 2. sides of red triangle is k times side of green triangle. Wite down your Observation in your own words : 1. Relationship between 2 triangles when k not equal to 1 2. Relationship between 2 triangles when k = 1  

Learning Summary

1. For 2 triangles, if Side, Angle, Side are equal, then they are congruent (SAS congruency) 2. For 2 triangles, if an Angle is equal, and the two sides including the the equal angle are in fixed ratio, then the 2 triangles are Similar.
