What Does Congruent Mean?

For Teachers 6th - 12th
Two figures are congruent if they have the same size and shape. Line segments can also be congruent if they are of the same length. Vertical angles created by intersecting lines are always congruent. Polygons that have matching angles...

Congruent Polygons: Copying Stretchy Shapes

For Teachers 3rd
Third graders investigate congruent polygons through dance. In this congruency lesson plan, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...
