First, make sure you understand that a circle is comprised of every point on a plane that is the same distance from a given center point. Therefore, all radii of a triangle are congruent.

Move points 'A' and 'B' to represent the desired lengths for segments 'a' and 'b'.

Questions to promote inquiry

What does this simulation indicate to you about the SSS Theorem? Why?

Are there not two triangles formed? Does the SSS Theorem signify congruent triangles?

What about the case when the two circles do not intersect? What does this tell you about necessary parts of a triangle?
