These triangles are at least close to congruent. Mathematicians say two shapes are congruent if and only if you can transform one onto the other using a combination of flips, slides and turns.
Two ways to play here:
-predict whether they're congruent using the checkboxes and check button, then investigate using motions.
OR
-investigate using motions, decide whether they are congruent or not, then check with the button.
Maybe try both ways!
