Today, we examined the concept of congruence.
congruent – the same shape and size
We learned that if you can rotate, shift, and/or flip an object so that it perfectly lines up with another, then those objects are congruent.
We want to be able to easily tell if triangles are congruent and we can do this through Congruence Shortcuts.
The first shortcut we examined was SSS where two triangles share the same three sides.
We used patty paper to arrange and examine triangles with the same sides and found that they were always congruent.
