Example 1

Determine which congruence statement, if any, can be used to show that [math]\triangle{\it PQR}[/math] and [math]\triangle{\it STU}[/math] are congruent. [i]Note[/i]: Drag points [math]P[/math], [math]Q[/math], and [math]R[/math] to try different figures. Drag point [math]U[/math] to move the second figure.

[list=1] [*]Determine which components of the triangles are congruent. [*]Determine if this information is enough to state that all six corresponding parts of the two triangles are congruent. [*]Summarize your findings. [/list] This applet is provided by Walch Education as supplemental material for their mathematics programs.
