MOTIONS:There are 3 different ways to

move a plane figure:

*SLIDE*FLIP*TURN

Page 8: GEOMETRY SLIDESHOW 2:. CONGRUENT Figures are the same SIZE and SHAPE CongruentNOT Congruent not same shape NOT Congruent not same size

*SLIDE – Translation

*FLIP – Reflection

*TURN - Rotation

SYMMETRY

A rectangle is a symmetric figure because it can be folded into 2 congruent halves

that fit on top of each other.

Each of your folds lie along a line of symmetry. The

rectangle has two lines of symmetry.
