Congruent Two shapes that are the same size and shape

symmetry a line of symmetry is when you divide a shape in half and both sides of the line are the same

Perpendicular Two lines that intersect at a 90˚ angle

parallel Two lines that do not touch and are equal distances away from each other.

vertices the corner of a 2D or 3D shape. The point where two lines meet.

Faces the flat surfaces of a 3D shape

Edges the place where two faces meet on a 3D figure

Polygon a closed figure with 3 or more sides

Triangle 2d 3 sides 1 face 3 vertices

Circle 2d 1 Face

Square 2d 4 sides of equal measure 1 face 4 vertices

Rectangle 2d 4 sides (2 with equal measure) 1 face 4 vertices

Rhombus 2d 4 sides 1 face 4 vertices

pentagon 2d 5 sides 1face 5 vertices

hexagon 2d 6 sides 1 face 6 vertices

octagon 2d 8 sides 1 face 8 vertices
