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.
