Attributes A quality that is characteristic of someone or something.

Congruent – figures that have exactly the same size and same shape

Lines parallel lines Lines in a plane that never intersect Example: perpendicular lines Two lines that intersect to form four right angles Example:

Trapezoid – a quadrilateral with only one pair of parallel sides

Parallelogram – any four sided polygon with two pairs of parallel lines

– A figure with 3 dimensions; not flat Solid figure

– having length, width, height, and volume Three Dimensional

Horizontal Horizontal – the direction from left to right V E R T I C A Vertical – The direction from top to bottom

– A place where two or more sides meet on a geometric solid Edge – A place where two or more sides meet on a geometric solid Edge

Face – A flat side on a geometric solid Face

Vertex – a corner; a place where three or more sides meet in a geometric solid

Prism – A 3-dimensional figure that has two congruent and parallel faces that are polygons. The rest of the faces are parallelograms Hexagonal prism rectangular prism

Rectangular Prism – A solid figure in which all six faces are rectangles

Square Pyramid – a pyramid whose base is a square and whose other faces are triangles that share a common vertex

Base – A special face of a solid figure The base of a cone is a circle.

Side – any of the line segments that form a polygon Side

Square – A plane figure with four sides that are the same length and four right angles

A parallelogram with four right angles Rectangle A parallelogram with four right angles

Triangle – A plane figure with three straight sides

Pentagon – a five-sided polygon

Hexagon – a six sided polygon 1 6 2 5 3 4

Octagon – An eight-sided polygon STOP

Cube – A solid figure with six congruent square faces

Pyramid – a polyhedron whose base is a polygon whose other faces are triangles that share a common vertex

Sphere – any round object whose curved surface is the same distance to the center as all of its points

– Cylinder A solid figure with two circular bases that are parallel and congruent

Cone – a solid figure with one curved surface, one circular base, and one vertex Vertex Circular Base
