Write down congruence of special five geometry figures |
|
Answer» s of points are CALLED CONGRUENT if, and only if, one can be transformed into the other by an isometry, i.e., a combination of RIGID motions, namely a translation, a rotation, and a reflection. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object. So TWO distinct PLANE figures on a piece of paper are congruent if we can cut them out and then match them up completely. Turning the paper over is permitted. |
