Pentomino | an arrangement of 5 identical squares in a plane. The squares must be attched to one another edge to edge. |
Line symmetry | a figure has line symmetry when it can be folded along one or mre lines that create congruent parts, which can fit on top of each other exactly. |
rotational symmetry | a figure has rotational symmetry when it can rotate onto itself in less than a full rotation. |
congruent | figures that have the same size and shape. |
translation | the change in the position of a figure that moves it up, down, or sideways. |
rotation | the change in the position of a figure that moves it around a point. |
line of symmetry | the fold line in a symmetric figure |
