plane figures	Plane figures are flat figures. They have length and width. They may be open or closed figures.
vertex, vertices	A point where two sides of a polygon meet.
quadrilaterals	Polygons with 4 sides and 4 angles.
parallelogram	A quadrilateral with two opposite sides that are parallel. Only the opposites sides of a parallelogram need to be equal.

turn	Rotate a figure about a point.

not congruent	Two figures that are either not the same shape or not the same size.
symmetry	Occurs when two halves of a figure fit each other exactly when folded along a line. Two halves are mirror images of each other.
line of symmetry	A line that divides a figure into congruent halves. The halves fit exactly over each other when folded along this line.
